Description

I. INTRODUCTION

The invention relates to synthesis of a crystalline or amorphous silicon hydride and the crystalline or amorphous silicon hydride.

II. BACKGROUND OF THE INVENTION

It was reported previously that a chemically generated or assisted plasma source has been developed [1-68, numbers in brackets refer to reference numbers in the Reference list disclosed herein below]. One such source operates by incandescently heating a hydrogen dissociator to provide atomic hydrogen and heats a catalyst such that it becomes gaseous and reacts with the atomic hydrogen to produce a plasma called a resonant transfer or rt-plasma. It was extraordinary, that intense EUV emission was observed [reference numbers 13, 15, 18-19, 23-24, 27, 30, 37, 42, 45, 49, 53-54, 56-58] at low temperatures (e.g. ≈10³ K) and an extraordinary low field strength of about 1-2 V/cm from atomic hydrogen and certain atomized elements or certain gaseous ions which singly or multiply ionize at integer multiples of the potential energy of atomic hydrogen, 27.2 eV. This is two orders of magnitude lower than the starting voltages measured for gas glow discharges [69-70]. A number of independent experimental observations confirm a novel reaction of atomic hydrogen which produces hydrogen in fractional quantum states that are at lower energies than the traditional “ground” (n=1) state, a chemically generated or assisted plasma (rt-plasma), and produces novel hydride compounds. These include extreme ultraviolet (EUV) spectroscopy [2-5, 7, 11, 13, 15-16, 18-20, 23-24, 26-27, 33-38, 40-42, 45, 49, 53-55, 57-58], characteristic emission from catalysis and the hydride ion products [4-5, 11, 13, 15, 18-19, 27, 30-31, 37, 42, 45, 53], lower-energy hydrogen emission [3, 7, 20, 33-36, 40-41], plasma formation [13, 15, 18-19, 23-24, 27, 30, 37, 42, 45, 49, 53-54, 56-58], Balmer α line broadening [1-7, 11, 13, 15-16, 18-19, 21, 24, 26-27, 30, 32-36, 39, 49, 53], population inversion of hydrogen lines [2, 4-5, 11, 13, 15-16, 19, 24, 30], elevated electron temperature [3, 6, 7, 21, 26, 32-35], anomalous plasma afterglow duration [23, 56-57], power generation [2, 7, 26, 30, 34-36, 38-39, 44, 46, 58, 65-67], and analysis of chemical compounds [1, 6, 8-10, 25, 28, 31, 44, 50, 59-63]. The reaction has applications as a new light source, a new field of hydrogen chemistry, and a new source of energy with direct plasma to electric power conversion possible [2, 14, 22, 29].

The theory given previously [12, 17, 47, 48, 52, 64, 68] is based on applying Maxwell's equations to the Schrödinger equation. The familiar Rydberg equation (Eq. (1)) arises for the hydrogen excited states for n>1 in Eq. (2).

$\begin{array}{cc}{E}_n=-\frac{{}^2}{n^28{\mathrm{\pi \varepsilon }}_oa_H}=-\frac{13.598\mathrm{eV}}{n^2}& \left(1\right)\end{array}$ n=1,2,3,  (2)

An additional result is that atomic hydrogen may undergo a catalytic reaction with certain atoms and ions which singly or multiply ionize at integer multiples of the potential energy of atomic hydrogen, m·27.2 e V wherein m is an integer. The reaction involves a nonradiative energy transfer to form a hydrogen atom that is lower in energy than unreacted atomic hydrogen that corresponds to a fractional principal quantum number. That is

$\begin{array}{cc}n=\frac{1}{2},\frac{1}{3},\frac{1}{4},\dots ,\frac{1}{p};p\mathrm{is}\mathrm{an}\mathrm{integer}& \left(3\right)\end{array}$

replaces the well known parameter n=integer in the Rydberg equation for hydrogen excited states. The n=1 state of hydrogen and the

$n=\frac{1}{\mathrm{integer}}$

states of hydrogen are nonradiative, but a transition between two nonradiative states is possible via a nonradiative energy transfer, say n=1 to n=½. Thus, a catalyst provides a net positive enthalpy of reaction of m·27.2 e V (i.e. it resonantly accepts the nonradiative energy transfer from hydrogen atoms and releases the energy to the surroundings to affect electronic transitions to fractional quantum energy levels). As a consequence of the nonradiative energy transfer, the hydrogen atom becomes unstable and emits further energy until it achieves a lower-energy nonradiative state having a principal energy level given by Eqs. (1) and (3). Processes such as hydrogen molecular bond formation that occur without photons and that require collisions are common [71]. Also, some commercial phosphors are based on resonant nonradiative energy transfer involving multipole coupling [72].

The catalyst products H(1/p) were predicted to be a highly reactive intermediates which further react to form a novel hydride ions H⁻(1/p) with predicted binding energies E_B given by the following formula [27, 37, 42, 59, 68]:

$\begin{array}{cc}{E}_B=\frac{{\hslash }^2\sqrt{s\left(s+1\right)}}{8{\mu }_e{a_0^2\left[\frac{1+\sqrt{s\left(s+1\right)}}{p}\right]}^2}-\frac{{\mathrm{\pi \mu }}_0e^2{\hslash }^2}{m_e^2}\left(\frac{1}{a_H^3}+\frac{2^2}{{a_0^3\left[\frac{1+\sqrt{s\left(s+1\right)}}{p}\right]}^3}\right)& \left(4\right)\end{array}$

where p is an integer greater than one, s=½, is Planck's constant bar, μ_o is the permeability of vacuum, m_e is the mass of the electron, μ_e is the reduced electron mass given by

${\mu }_e=\frac{m_em_p}{\frac{m_e}{\sqrt{\frac{3}{4}}}+m_p}$

where m_p is the mass of the proton, α_H is the radius of the hydrogen atom, α_o is the Bohr radius, and e is the elementary charge. The ionic radius is

$\begin{array}{cc}{r}_1=\frac{a_0}{p}\left(1+\sqrt{s\left(s+1\right)}\right)s=\frac{1}{2}& \left(5\right)\end{array}$

Rb⁺ to Rb²⁺ and 2K⁺ to K+K²⁺ each fulfill the catalyst criterion—a chemical or physical process with an enthalpy change equal to an integer multiple of to the potential energy of atomic hydrogen, 27.2 eV. Mills et al. have reported an energetic catalytic reaction involving a resonant energy transfer between hydrogen atoms and Rb⁺ or 2K⁺ to form an rt-plasma with a very stable novel hydride ion product [13, 27, 37, 42]. Its predicted binding energy of 3.0468 eV with the fine structure was observed at 407.1 nm, and its predicted bound-free hyperfine structure lines E_HF=j²3.00213×10⁻⁵+3.0563 eV (j is an integer) matched those observed for j=1 to j=38 to within a 1 part per 10⁵. Hydride ions with high binding energies and upfield shifted peaks have been observed by XPS and by solid state magic-angle spinning proton nuclear magnetic resonance (¹H MAS NMR), respectively [8, 25, 28, 31, 50, 59-63].

He⁺ serves as a catalyst since the second ionization energy of helium is 54.417 eV, which is equivalent to 2·27.2 eV. In this case, 54.417 eV is transferred nonradiatively from atomic hydrogen to He⁺ which is resonantly ionized. The electron decays to the n=⅓ state with the further release of 54.417 eV which may be emitted as a photon. Since the products of the catalysis reaction have binding energies of m·27.2 eV, they may further serve as catalysts. Thus, further catalytic transitions may occur:

$n=\frac{1}{3}->\frac{1}{4},\frac{1}{4}->\frac{1}{5},$

and so on which may further react to form novel hydrides. Extremely stable hydride ions may stabilize a silicon surface to unprecedented time scales to increase the yield in integrated chip fabrication.

Aqueous HF acid etching of silicon surfaces results in the removal of the surface oxide and produces hydrogen terminated silicon surfaces, Si—H. HF etching is a key step in producing silicon surfaces which are contamination-free and chemically stable for subsequent processing in the semiconductor industry [73-75]. In fact, chemical oxidation and subsequent HF treatment of Si surfaces are used prior to gate oxidation, where surface contamination (<10 ppm level) and interface control are crucial to device performance. Fluorine termination was initially considered the basis of the chemical stability of HF-treated surfaces. Subsequently, it was found that fluorine is a minor species on the surface and that the remarkable surface passivation achieved by HF is explained by H termination of silicon dangling bonds protecting the surface from chemical attack [75-77]. However, the replacement of the oxide layer with the H termination of the silicon dangling bonds by HF can be attributed to the increased electronegativity of fluoride ion versus oxide causing an enhanced reactivity of H⁺ which attacks the oxide layer. The electron affinity of halogens increases from the bottom of the Group VII elements to the top. Hydride ion may be considered a halide since it possess the same electronic structure. And, according to the binding energy trend, it should have a high binding energy. However, the binding energy is only 0.75 e V which is much lower than the 3.4 e V binding energy of a fluoride ion. And, once the HF is rinsed from the surface, the Si—H layer undergoes rapid oxidation when exposed to oxygen or solvents containing oxygen. An Si—H layer with enhanced stability would be of great value to the semiconductor industry.

Amorphous Si—H films, the active component of important semiconductor devices such as photovoltaics, optoelectronics, liquid crystal displays, and field-effect transistors are formed by plasma enhanced chemical vapor deposition (PECVD) techniques [78]. Typically the film is grown on a silicon wafer substrate exposed to a plasma of silane, hydrogen, and often argon using a reactor with a diode configuration in which the plasma is confined between two parallel electrodes. These films are air sensitive. An alternative approach to achieve oxidation resistant Si—H is by the synthesize of a novel amorphous silicon hydride surface coating designated α-SiH(1/p) using a catalytic plasma reaction. For example, silane is reacted in a helium-hydrogen microwave discharge plasma at the surface of a substrate such as a nickel foil. The novel α—SiH(1/p) comprises high-binding-energy hydride ions which provide extreme stability to air. The novel α-SiH(1/p) film may advance semiconductor fabrication and devices.

The binding energy of an atom, ion, or molecule, also known as the ionization energy, is the energy required to remove one electron from the atom, ion or molecule. A hydrogen atom having the binding energy given in Eq. (6) is hereafter referred to as a hydrino atom or hydrino. The designation for a hydrino of radius

$\frac{a_H}{p},$

where α_H is the radius of an ordinary hydrogen atom and p is an integer, is

$H\left[\frac{a_H}{p}\right].$

A hydrogen atom with a radius α_H is hereinafter referred to as “ordinary hydrogen atom” or “normal hydrogen atom.” Ordinary atomic hydrogen is characterized by its binding energy of 13.6 eV.

Hydrinos are formed by reacting an ordinary hydrogen atom with a catalyst having a net enthalpy of reaction of about

m·27.2eV  (7a)

where m is an integer. This catalyst has also been referred to as an energy hole or source of energy hole in Mills earlier filed Patent Applications. It is believed that the rate of catalysis is increased as the net enthalpy of reaction is more closely matched to m·27.2 eV. It has been found that catalysts having a net enthalpy of reaction within ±10%, preferably ±5%, of m·27.2 eV are suitable for most applications.

In another embodiment, the catalyst to form hydrinos has a net enthalpy of reaction of about

m/2·27.2eV  (7b)

where m is an integer greater that one. It is believed that the rate of catalysis is increased as the net enthalpy of reaction is more closely matched to m/2·27.2 eV. It has been found that catalysts having a net enthalpy of reaction within ±10%, preferably ±5%, of m/2·27.2 eV are suitable for most applications. The catalyst are given in Mills Prior Publications such as those given in TABLES 1 and 3 of my prior PCT Appl. No. PCT/US02/06945 filed November 2002 and the Tables of the Prior Mills Publications (e.g. TABLE 4 of PCT/US90/01998 and pages 25-46, 80-108 of PCT/US94/02219). The catalyst may be at least one molecule selected from the group of C₂, N₂, O₂, CO₂, NO₂, and NO₃ or at least one atom, ion, or excimer selected from the group of Li, Be, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Kr, Rb, Sr, Nb, Mo, Pd, Sn, Te, Cs, Ce, Pr, Sm, Gd, Dy, Pb, Pt, Kr, He⁺, Na⁺, Rb⁺, Sr⁺, Fe³⁺, Mo²⁺, Mo⁴⁺, In³⁺, He⁺, Ne⁺, Ar⁺, Xe⁺, H, H(1/p), Ar^{2+ and H+}, and Ne⁺ and H⁺, Ne₂*, and He₂*.

The hydrino hydride ion of the present invention can be formed by the reaction of an electron source with a hydrino, that is, a hydrogen atom having a binding energy of about

$\frac{13.6\mathrm{eV}}{n^2},$

where

$n=\frac{1}{p}$

and p is an integer greater than 1. The hydrino hydride ion is represented by H⁻(n=1/p) or H⁻(1/p):

$\begin{array}{cc}H\left[\frac{a_H}{p}\right]+e^{-}->H^{-}\left(n=1\text{/}p\right)& \left(8a\right)\\ H\left[\frac{a_H}{p}\right]+e^{-}->H^{-}\left(1\text{/}p\right)& \left(8b\right)\end{array}$

The hydrino hydride ion is distinguished from an ordinary hydride ion comprising an ordinary hydrogen nucleus and two electrons having a binding energy of about 0.8 eV. The latter is hereafter referred to as “ordinary hydride ion” or “normal hydride ion” The hydrino hydride ion comprises a hydrogen nucleus including proteum, deuterium, or tritium, and two indistinguishable electrons at a binding energy according to Eq. (9).

The binding energy of a novel hydrino hydride ion can be represented by the following formula:

$\begin{array}{cc}\mathrm{Binding}\mathrm{Energy}=\frac{{\hslash }^2\sqrt{s\left(s+1\right)}}{8{\mu }_e{a_0^2\left[\frac{1+\sqrt{s\left(s+1\right)}}{p}\right]}^2}-\frac{{\mathrm{\pi \mu }}_0{}^2{\hslash }^2}{m_e^2}\left(\frac{1}{a_H^3}+\frac{2^2}{{a_0^3\left[\frac{1+\sqrt{s\left(s+1\right)}}{p}\right]}^3}\right)& \left(9\right)\end{array}$

where p is an integer greater than one, s=½, π is pi, is Planck's constant bar, μ_o is the permeability of vacuum, m_e is the mass of the electron, μ_e is the reduced electron mass given by

${\mu }_e=\frac{m_em_p}{\frac{m_e}{\sqrt{\frac{3}{4}}}+m_p}$

where m_p is the mass of the proton, α_H is the radius of the hydrogen atom, α_o is the Bohr radius, and e is the elementary charge. The radii are given by

$\begin{array}{cc}{r}_2=r_1=a_0\left(1+\sqrt{s\left(s+1\right)}\right);s=\frac{1}{2}& \left(10\right)\end{array}$

The binding energies of the hydrino hydride ion, H⁻(n=1/p) as a function of p, where p is an integer, are shown in TABLE 1.

The existence of novel alkaline and alkaline earth hydride and halido-hydrides were previously identified by large distinct upfield ¹H NMR resonances compared to the NMR peaks of the corresponding ordinary hydrides [R. Mills, B. Dhandapani, M. Nansteel, J. He, T. Shannon, A. Echezuria, “Synthesis and Characterization of Novel Hydride Compounds”, Int. J. of Hydrogen Energy, Vol. 26, No. 4, (2001), pp. 339-367; R. Mills, B. Dhandapani, N. Greenig, J. He, “Synthesis and Characterization of Potassium Iodo Hydride”, Int. J. of Hydrogen Energy, Vol. 25, Issue 12, December, (2000), pp. 1185-1203; R. Mills, B. Dhandapani, M. Nansteel, J. He, A. Voigt, “Identification of Compounds Containing Novel Hydride Ions by Nuclear Magnetic Resonance Spectroscopy”, Int. J. Hydrogen Energy, Vol. 26, No. 9, (2001), pp. 965-979]. Using a number of analytical techniques such as XPS and time-of-flight-secondary-mass-spectroscopy (ToF-SIMS) as well as NMR, the hydrogen content was assigned to H⁻(1/p), novel high-binding-energy hydride ions in stable fractional principal quantum states [R. Mills, B. Dhandapani, M. Nansteel, J. He, T. Shannon, A. Echezuria, “Synthesis and Characterization of Novel Hydride Compounds”, Int. J. of Hydrogen Energy, Vol. 26, No. 4, (2001), pp. 339-367; R. Mills, B. Dhandapani, N. Greenig, J. He, “Synthesis and Characterization of Potassium Iodo Hydride”, Int. J. of Hydrogen Energy, Vol. 25, Issue 12, December, (2000), pp. 1185-1203; R. L. Mills, B. Dhandapani, J. He, “Highly Stable Amorphous Silicon Hydride”, Solar Energy Materials & Solar Cells, submitted]. The synthesis reactions typically involve metal ion catalysts. For example, Rb⁺ to Rb²⁺ and 2K⁺ to K+K²⁺ each provide a reaction with a net enthalpy equal to the potential energy of atomic hydrogen. It was reported previously [R. L. Mills, P. Ray, “A Comprehensive Study of Spectra of the Bound-Free Hyperfine Levels of Novel Hydride Ion H⁻(½), Hydrogen, Nitrogen, and Air”, Int. J. Hydrogen Energy, in press] that the presence of these gaseous ions with thermally dissociated hydrogen formed a hydrogen plasma with hydrogen atom energies of 17 and 12 eV respectively, compared to 3 eV for a hydrogen microwave plasma. The energetic catalytic reaction involves a resonance energy transfer between hydrogen atoms and Rb⁺ or 2K⁺ to form a very stable novel hydride ion H⁻(½). Its predicted binding energy of 3.0468 e V was observed by high resolution visible spectroscopy as a continuum threshold at 406.82 nm, and a structured, strong emission peak was observed at 407.1 nm corresponding to the fine structure and hyperfine structure of H(½). From the electron g factor, bound-free hyperfine structure lines of H⁻(½) were predicted with energies E_HF given by E_HF=j²3.00213×10⁻⁵+3.0563 eV (j is an integer) as an inverse Rydberg-type series from 3.0563 eV to 3.1012 eV—the hydride binding energy peak with the fine structure plus one and five times the spin-pairing energy, respectively. The high resolution visible plasma emission spectra in the region of 399.5 to 406.0 nm matched the predicted emission lines for j=1 to j=39 with the series edge at 399.63 nm up to 1 part in 10⁵.

SUMMARY OF THE INVENTIONS

An object of the present invention is to generate power and novel hydrogen species and compositions of matter comprising new forms of hydrogen via the catalysis of atomic hydrogen.

Another object of the present invention is to synthesize silicon hydride (SiH(1/p)) thin films on substrates that have enhanced stability to oxidation due to the incorporation of increased binding energy species. The films may be amorphous or crystalline.

The above objectives and other objectives are achieved by the present invention comprising a power source and hydrogen reactor to form silicon hydride SiH(1/p) in crystalline or amorphous form. SiH(1/p) may be formed as a film on a substrate. SiH(1/p) comprises silicon and at least one increased binding energy hydrogen species. SiH(1/p) may comprise silicon that is terminated with an increased binding energy hydrogen species. In an embodiment SiH(1/p) comprises hydrino terminated silicon.

The power source and reactor comprises a cell for the catalysis of atomic hydrogen to form novel hydrogen species and compositions of matter comprising new forms of hydrogen. The novel hydrogen compositions of matter comprise:

(a) at least one neutral, positive, or negative hydrogen species (hereinafter “increased binding energy hydrogen species”) having a binding energy

• • (i) greater than the binding energy of the corresponding ordinary hydrogen species, or
  • (ii) greater than the binding energy of any hydrogen species for which the corresponding ordinary hydrogen species is unstable or is not observed because the ordinary hydrogen species' binding energy is less than thermal energies at ambient conditions (standard temperature and pressure, STP), or is negative; and

(b) at least one other element. The compounds of the invention are hereinafter referred to as “increased binding energy hydrogen compounds”.

By “other element” in this context is meant an element other than an increased binding energy hydrogen species. Thus, the other element can be an ordinary hydrogen species, or any element other than hydrogen. In one group of compounds, the other element and the increased binding energy hydrogen species are neutral. In another group of compounds, the other element and increased binding energy hydrogen species are charged such that the other element provides the balancing charge to form a neutral compound. The former group of compounds is characterized by molecular and coordinate bonding; the latter group is characterized by ionic bonding. The other element may be silicon in any oxidation state.

Also provided are novel compounds and molecular ions comprising

(a) at least one neutral, positive, or negative hydrogen species (hereinafter “increased binding energy hydrogen species”) having a total energy

• • (i) greater than the total energy of the corresponding ordinary hydrogen species, or
  • (ii) greater than the total energy of any hydrogen species for which the corresponding ordinary hydrogen species is unstable or is not observed because the ordinary hydrogen species' total energy is less than thermal energies at ambient conditions, or is negative; and

(b) at least one other element. The other element may be silicon in any oxidation state.

The total energy of the hydrogen species is the sum of the energies to remove all of the electrons from the hydrogen species. The hydrogen species according to the present invention has a total energy greater than the total energy of the corresponding ordinary hydrogen species. The hydrogen species having an increased total energy according to the present invention is also referred to as an “increased binding energy hydrogen species” even though some embodiments of the hydrogen species having an increased total energy may have a first electron binding energy less that the first electron binding energy of the corresponding ordinary hydrogen species. For example, the hydride ion of Eq. (9) for p=24 has a first binding energy that is less than the first binding energy of ordinary hydride ion, while the total energy of the hydride ion of Eq. (9) for p=24 is much greater than the total energy of the corresponding ordinary hydride ion.

Also provided are novel compounds and molecular ions comprising

(a) a plurality of neutral, positive, or negative hydrogen species (hereinafter “increased binding energy hydrogen species”) having a binding energy

• • (i) greater than the binding energy of the corresponding ordinary hydrogen species, or
  • (ii) greater than the binding energy of any hydrogen species for which the corresponding ordinary hydrogen species is unstable or is not observed because the ordinary hydrogen species' binding energy is less than thermal energies at ambient conditions or is negative; and

(b) optionally one other element. The compounds of the invention are hereinafter referred to as “increased binding energy hydrogen compounds”.

The increased binding energy hydrogen species can be formed by reacting one or more hydrino atoms with one or more of an electron, hydrino atom, a compound containing at least one of said increased binding energy hydrogen species, and at least one other atom, molecule, or ion other than an increased binding energy hydrogen species.

Also provided are novel compounds and molecular ions comprising

(a) a plurality of neutral, positive, or negative hydrogen species (hereinafter “increased binding energy hydrogen species”) having a total energy

• • (i) greater than the total energy of ordinary molecular hydrogen, or
  • (ii) greater than the total energy of any hydrogen species for which the corresponding ordinary hydrogen species is unstable or is not observed because the ordinary hydrogen species' total energy is less than thermal energies at ambient conditions or is negative; and

(b) optionally one other element. The other element may be silicon. The compounds of the invention are hereinafter referred to as “increased binding energy hydrogen compounds”.

The total energy of the increased total energy hydrogen species is the sum of the energies to remove all of the electrons from the increased total energy hydrogen species. The total energy of the ordinary hydrogen species is the sum of the energies to remove all of the electrons from the ordinary hydrogen species. The increased total energy hydrogen species is referred to as an increased binding energy hydrogen species, even though some of the increased binding energy hydrogen species may have a first electron binding energy less than the first electron binding energy of ordinary molecular hydrogen. However, the total energy of the increased binding energy hydrogen species is much greater than the total energy of ordinary molecular hydrogen.

In one embodiment of the invention, the increased binding energy hydrogen species can be H_n, and H_n⁻ where n is a positive integer, or H_n⁺ where n is a positive integer greater than one. Preferably, the increased binding energy hydrogen species is H_n and H_n⁻ where n is an integer from one to about 1×10⁶, more preferably one to about 1×10⁴, even more preferably one to about 1×10², and most preferably one to about 10, and H_n⁺ where n is an integer from two to about 1×10⁶, more preferably two to about 1×10⁴, even more preferably two to about 1×10², and most preferably two to about 10. A specific example of H_n⁻ is H₁₆⁻.

In an embodiment of the invention, the increased binding energy hydrogen species can be H_n^m− where n and m are positive integers and H_n^m+ where n and m are positive integers with m<n. Preferably, the increased binding energy hydrogen species is H_n^m− where n is an integer from one to about 1×10⁶, more preferably one to about 1×10⁴, even more preferably one to about 1×10², and most preferably one to about 10 and m is an integer from one to 100, one to ten, and H_n^m+ where n is an integer from two to about 1×10⁶, more preferably two to about 1×10⁴, even more preferably two to about 1×10², and most preferably two to about 10 and m is one to about 100, preferably one to ten.

According to a preferred embodiment of the invention, a compound is provided, comprising at least one increased binding energy hydrogen species selected from the group consisting of (a) hydride ion having a binding energy according to Eq. (9) that is greater than the binding of ordinary hydride ion (about 0.8 eV) for p=2 up to 23, and less for p=24 (“increased binding energy hydride ion” or “hydrino hydride ion”); (b) hydrogen atom having a binding energy greater than the binding energy of ordinary hydrogen atom (about 13.6 eV) (“increased binding energy hydrogen atom” or “hydrino”); (c) hydrogen molecule having a first binding energy greater than about 15.3 eV (“increased binding energy hydrogen molecule” or “dihydrino”); and (d) molecular hydrogen ion having a binding energy greater than about 16.3 eV (“increased binding energy molecular hydrogen ion” or “dihydrino molecular ion”).

The compounds of the present invention are capable of exhibiting one or more unique properties which distinguishes them from the corresponding compound comprising ordinary hydrogen, if such ordinary hydrogen compound exists. The unique properties include, for example, (a) a unique stoichiometry; (b) unique chemical structure; (c) one or more extraordinary chemical properties such as conductivity, melting point, boiling point, density, and refractive index; (d) unique reactivity to other elements and compounds; (e) enhanced stability at room temperature and above; and/or (f) enhanced stability in air and/or water.

(9) that is greater than the binding of ordinary hydride ion (about 0.8 eV) for p=2 up to 23, and less for p=24 (H⁻) is provided. For p=2 to p=24 of Eq. (9), the hydride ion binding energies are respectively 3, 6.6, 11.2, 16.7, 22.8, 29.3, 36.1, 42.8, 49.4, 55.5, 61.0, 65.6, 69.2, 71.6, 72.4, 71.6, 68.8, 64.0, 56.8, 47.1, 34.7, 19.3, and 0.69 eV.

DETAILED DESCRIPTION OF THE INVENTION

The following preferred embodiments of the invention disclose numerous property ranges, including but not limited to, plasma power densities, gas pressure, mole fractions of reactants and catalysts, flow rates, temperature, and the like, which are merely intended as illustrative examples. Based on the detailed written description, one skilled in the art would easily be able to practice this invention within other property ranges to produce the desired result without undue experimentation.

1. Hydrogen RF and Microwave Power and Plasma Cell and Reactor

According to an embodiment of the invention, a reactor for producing power, plasma, and at least one of hydrinos, hydrino hydride ions, dihydrino molecular ions, and dihydrino molecules that react with a source of silicon to form α-SiH(1/p) may take the form of a hydrogen microwave reactor. A hydrogen microwave gas cell reactor of the present invention is shown in FIG. 1. Hydrinos are provided by a reaction with a catalyst capable of providing a net enthalpy of reaction of m/2·27.2±0.5 eV where m is an integer, preferably an integer less than 400 such as those given in TABLES 1 and 3 of my Prior PCT Appl. No. PCT/US02/06945 filed November 2002 and/or by a disproportionation reaction wherein lower-energy hydrogen, hydrinos, serve to cause transitions of hydrogen atoms and hydrinos to lower-energy levels with the release of power. Catalysis may occur in the gas phase. The catalyst may be generated by a microwave discharge. Preferred catalysts are He⁺ or Ar⁺ from a source such as helium gas or argon gas. The catalysis reaction may provide power to form and maintain a plasma that comprises energetic ions.

The reactor system of FIG. 1 comprises a reaction vessel 601 having a chamber 660 capable of containing a vacuum or pressures greater than atmospheric. A source of hydrogen 638 delivers hydrogen to supply tube 642, and hydrogen flows to the chamber through hydrogen supply passage 626. The flow of hydrogen can be controlled by hydrogen flow controller 644 and valve 646. In an embodiment, a source of hydrogen communicating with chamber 660 that delivers hydrogen to the chamber through hydrogen supply passage 626 is a hydrogen permeable hollow cathode of an electrolysis cell of the reactor system. Electrolysis of water produces hydrogen that permeates through the hollow cathode. The cathode may be a transition metal such as nickel, iron, or titanium, or a noble metal such as palladium, or platinum, or tantalum or palladium coated tantalum, or palladium coated niobium. The electrolyte may be basic and the anode may be nickel, platinum, or a dimensionally stable anode. The electrolyte may be aqueous K₂CO₃. The flow of hydrogen into the cell may be controlled by controlling the electrolysis current with an electrolysis power controller.

Plasma gas flows from the plasma gas supply 612 via passage 632. The flow of plasma gas can be controlled by plasma gas flow controller 634 and valve 636. A mixture of plasma gas and hydrogen can be supplied to the cell via passage 626. The mixture is controlled by hydrogen-plasma-gas mixer and mixture flow regulator 621. The plasma gas such as helium may be a source of catalyst such as He⁺ or He₂*, argon may be a source of catalyst such as Ar⁺, neon may serve as a source of catalyst such as Ne₂* or Ne⁺, and neon-hydrogen mixture may serve as a source of catalyst such as Ne⁺/H⁺. The source of catalyst and hydrogen of the mixture flow into the plasma and become catalyst and atomic hydrogen in the chamber 660.

The plasma may be powered by a microwave generator 624 wherein the microwaves are tuned by a tunable microwave cavity 622, carried by waveguide 619, and can be delivered to the chamber 660 though an RF transparent window 613 or antenna 615. Sources of microwaves known in the art are traveling wave tubes, klystrons, magnetrons, cyclotron resonance masers, gyrotrons, and free electron lasers. The waveguide or antenna may be inside or outside of the cell. In the latter case, the microwaves may penetrate the cell from the source through a window of the cell 613. The microwave window may comprise Alumina or quartz.

In another embodiment, the cell 601 is a microwave resonator cavity. In an embodiment, the source of microwave supplies sufficient microwave power density to the cell to ionize a source of catalyst such as at least one of helium, neon-hydrogen mixture, and argon gases to form a catalyst such as He⁺, Ne⁺, and Ar⁺, respectively. In such an embodiment, the microwave power source or applicator such as an antenna, waveguide, or cavity forms a nonthermal plasma wherein the species corresponding to the source of catalyst such as helium or argon atoms and ions have a higher temperature than that at thermal equilibrium. Thus, higher energy states such as ionized states of the source of catalyst are predominant over that of hydrogen compared to a corresponding thermal plasma wherein excited states of hydrogen are predominant. In an embodiment, the source of catalyst is in excess compared to the source of hydrogen atoms such that the formation of a nonthermal plasma is favored. The power supplied by the source of microwave power may be delivered to the cell such that it is dissipated in the formation of energetic electrons within about the electron mean free path. In an embodiment, the total pressure is about 0.5 to about 5 Torr and the mean electron free path is about 0.1 cm to 1 cm. In an embodiment, the dimensions of the cell are greater than the electron mean free path.

In an embodiment, the cavity is at least one of the group of a reentrant cavity such as an Evenson cavity, Beenakker, McCarrol, and cylindrical cavity. In an embodiment, the cavity provides a strong electromagnetic field which may form a nonthermal plasma. The strong electromagnetic field may be due to a TM₀₁₀ mode of a cavity such as a Beenakker cavity. In a preferred embodiment, the cavity provides an E mode rather than an M mode. In a preferred embodiment, the cavity is a reentrant cavity such as an Evenson cavity that forms a plasma with an E mode. Multiple sources of microwave power may be used simultaneously. For example, the microwave plasma such as a nonthermal plasma may be maintained by multiple Evenson cavities operated in parallel to form the plasma in the microwave cell 601. The cell may be cylindrical and may comprise a quartz cell with Evenson cavities spaced along the longitudinal axis. In another embodiment, a multi slotted antenna such as a planar antenna serves as the equivalent of multiple sources of microwaves such as dipole-antenna-equivalent sources. One such embodiment is given in Y. Yasaka, D. Nozaki, M. Ando, T. Yamamoto, N. Goto, N. Ishii, T. Morimoto, “Production of large-diameter plasma using multi-slotted planar antenna,” Plasma Sources Sci. Technol., Vol. 8, (1999), pp. 530-533 which is incorporated herein by reference in its entirety.

In an embodiment, of the hydrogen microwave power and plasma cell and reactor, the output power is optimized by using a cavity such as a reentrant cavity such as an Evenson cavity and tuning the cell to an optimal voltage staging wave. In an embodiment, the reflected versus input power is tuned such that a desired voltage standing wave is obtained which optimizes or controls the output power. Typically, the ratio of the maximum voltage to the minimum voltage on the transmission line determines the voltage standing wave. In another embodiment, the cell comprises a tunable microwave cavity having a desired voltage standing wave to optimize and control the output power.

The cell may further comprise a magnet such a solenoidal magnet 607 to provide an axial magnetic field. The ions such as electrons formed by the hydrogen catalysis reaction produce microwaves to at least partially maintain the microwave discharge plasma. The microwave frequency may be selected to efficiently form atomic hydrogen from molecular hydrogen. It may also effectively form ions that serve as catalysts from a source of catalyst such as He⁺, Ne⁺, Ne⁺/H⁺, or Ar⁺ catalysts from helium, neon, neon-hydrogen mixtures, and argon gases, respectively.

The microwave frequency is preferably in the range of about 1 MHz to about 100 GHz, more preferably in the range about 50 MHz to about 10 GHz, most preferably in the range of about 75 MHz±50 MHz or about 2.4 GHz±1 GHz.

A vacuum pump 610 may be used to evacuate the chamber 660 through vacuum lines 648 and 650. The cell may be operated under flow conditions with the hydrogen and the catalyst supplied continuously from catalyst source 612 and hydrogen source 638. The amount of gaseous catalyst may be controlled by controlling the plasma gas flow rate where the plasma gas includes a hydrogen and a source of catalyst (e.g., hydrogen and argon or helium). The amount of gaseous hydrogen atoms to the plasma may be controlled by controlling the hydrogen flow rate and the ratio of hydrogen to plasma gas in the mixture. The hydrogen flow rate and the plasma gas flow rate to the hydrogen-plasma-gas mixer and mixture flow regulator 621 are controlled by flow rate controllers 634 and 644, and by valves 636 and 646. Mixer regulator 621 controls the hydrogen-plasma mixture to the chamber 660. The catalysis rate is also controlled by controlling the temperature of the plasma with microwave generator 624.

Catalysis may occur in the gas phase. Hydrino atoms, dihydrino molecular ions, dihydrino molecules, and hydrino hydride ions are produced in the plasma 604. Dihydrino molecules and hydrino hydride compounds such as α-SiH(1/p) may be cryopumped onto the wall 606, or they may flow into a 608 such as a cryotrap through passage 648. Trap 608 communicates with vacuum pump 610 through vacuum line 650 and valve 652. A flow to the trap 608 can be effected by a pressure gradient controlled by the vacuum pump 610, vacuum line 650, and vacuum valve 652.

In another embodiment of the hydrogen microwave reactor shown in FIG. 1, the wall 606 has a catalyst supply passage 656 for passage of the gaseous catalyst from a catalyst reservoir 658 to the plasma 604. The catalyst in the catalyst reservoir 658 can be heated by a catalyst reservoir heater 666 having a power supply 668 to provide the gaseous catalyst to the plasma 604. The catalyst vapor pressure can be controlled by controlling the temperature of the catalyst reservoir 658 by adjusting the heater 666 with its power supply 668. The catalyst in the gas phase may comprise those given in TABLES 1 and 3 of my prior PCT Appl. No. PCT/US02/06945 filed November 2002, hydrinos, and those described in the Mills Prior Publication.

A source of silicon may also be delivered to the reaction by the same means and methods as the catalyst, hydrogen, and plasma gas such that increased binding energy hydrogen species react with silicon to form α-SiH(1/p).

In another embodiment of the hydrogen microwave reactor, a chemically resistant open container such as a ceramic boat located inside the chamber 660 contains the catalyst. The reactor further comprises a heater that may maintain an elevated temperature. The cell can be operated at an elevated temperature such that the catalyst in the boat is sublimed, boiled, or volatilized into the gas phase. Alternatively, the catalyst in the catalyst boat can be heated with a boat heater having a power supply to provide the gaseous catalyst to the plasma. The catalyst vapor pressure can be controlled by controlling the temperature of the cell with a cell heater, or by controlling the temperature of the boat by adjusting the boat heater with an associated power supply. A source of silicon may also be delivered to the reaction by the same means and methods as the catalyst such that increased binding energy hydrogen species react with silicon to form α-SiH(1/p).

In an embodiment, the hydrogen microwave reactor further comprises a structure interact with the microwaves to cause localized regions of high electric and/or magnetic field strength. A high magnetic field may cause electrical breakdown of the gases in the plasma chamber 660. The electric field may form a nonthermal plasma that increases the rate of catalysis by methods such as the formation of the catalyst from a source of catalyst. The source of catalyst may be argon, neon hydrogen mixture, helium to form He⁺, Ne⁺, and Ar⁺, respectively. The structures and methods are equivalent to those given in the Plasma Torch Cell Hydride Reactor section of my previous PCT Appl. No. PCT/US02/35872 filed March 2002.

The nonthermal plasma temperature corresponding to the energetic ion and/or electron temperature as opposed to the relatively low energy thermal neutral gas temperature in the microwave cell reactor is advantageously maintained in the range of about 5,000-5,000,000° C. The cell may be operated without heating or insulation. Alternatively, in the case that the catalyst has a low volatility, the cell temperature is maintained above that of the catalyst source, catalyst reservoir 658 or catalyst boat to prevent the catalyst from condensing in the cell. The operating temperature depends, in part, on the nature of the material comprising the cell. The temperature for a stainless steel alloy cell is preferably about 0-1200° C. The temperature for a molybdenum cell is preferably about 0-1800° C. The temperature for a tungsten cell is preferably about 0-3000° C. The temperature for a glass, quartz, or ceramic cell is preferably about 0-1800° C.

The molecular and atomic hydrogen partial pressures in the chamber 660, as well as the catalyst partial pressure, is preferably maintained in the range of about 1 mtorr to about 100 atm. Preferably the pressure is in the range of about 100 mtorr to about 1 atm, more preferably the pressure is about 100 mtorr to about 20 torr.

An exemplary plasma gas for the hydrogen microwave reactor is argon. Exemplary flow rates are about 0.1 standard liters per minute (slm) hydrogen and about 1 slm argon. An exemplary forward microwave input power is about 1000 W. The flow rate of the plasma gas or hydrogen-plasma gas mixture such as at least one gas selected for the group of hydrogen, argon, helium, argon-hydrogen mixture, helium-hydrogen mixture, water vapor, ammonia is preferably about 0-1 standard liters per minute per cm³ of vessel volume and more preferably about 0.001-10 sccm per cm³ of vessel volume. In the case of an helium-hydrogen, neon-hydrogen, or argon-hydrogen mixture, preferably helium, neon, or argon is in the mole percentage range of about 99 to about 1%, more preferably about 99 to about 95%. The power density of the source of plasma power is preferably in the range of about 0.01 W to about 100 W/cm³ vessel volume.

In other embodiments of the microwave reactor, the catalyst may be agitated and supplied through a flowing gas stream such as the hydrogen gas or plasma gas which may be an additional source of catalyst such as helium or argon gas. The source of catalyst may also be provided by an aspirator, atomizer, or nebulizer to form an aerosol of the source of catalyst.

EXPERIMENTAL

A novel highly stable silicon hydride (SiH(1/p)) surface coating which comprised high binding energy hydride ions was synthesized by a microwave plasma reaction of a mixture of silane, hydrogen, and helium wherein He⁺ served as a catalyst with atomic hydrogen to form the highly stable hydride ions. Novel silicon hydride was identified by time of flight secondary ion mass spectroscopy and X-ray photoelectron spectroscopy. The time of flight secondary ion mass spectroscopy (ToF-SIMS) identified the coatings as hydride by the large SiH⁺ peak in the positive spectrum and the dominant H⁻ in the negative spectrum. X-ray photoelectron spectroscopy (XPS) identified the H content of the SiH coatings as hydride ions, H⁻(¼), H⁻( 1/9), and H⁻( 1/11) corresponding to peaks at 11, 43, and 55 eV, respectively. The silicon hydride surface was remarkably stable to air as shown by XPS. The highly stable amorphous silicon hydride coating may advance the production of integrated circuits and microdevices by resisting the oxygen passivation of the surface and possibly altering the dielectric constant and band gap to increase device performance.

The plasma which formed SiH(1/p) showed a number of extraordinary features. Novel emission lines with energies of q·13.6 eV where q=1, 2, 3, 4, 6, 7, 8, 9, or 11 were previously observed by extreme ultraviolet (EUV) spectroscopy recorded on microwave discharges of helium with 2% hydrogen [R. Mills, P. Ray, “Spectral Emission of Fractional Quantum Energy Levels of Atomic Hydrogen from a Helium-Hydrogen Plasma and the Implications for Dark Matter”, Int. J. Hydrogen Energy, Vol. 27, No. 3, pp. 301-322]. These lines matched H(1/p), fractional Rydberg states of atomic hydrogen where p is an integer, formed by a resonant nonradiative energy transfer to He⁺ acting as a catalyst. The average hydrogen atom temperature of the helium-hydrogen plasma was measured to be 180-210 e V versus ≈3 eV for pure hydrogen. Using water bath calorimetry, excess power was observed from the helium-hydrogen plasma compared to control krypton plasma. For example, for an input of 8.1 W, the total plasma power of the helium-hydrogen plasma measured by water bath calorimetry was 30.0 W corresponding to 21.9 W of excess power in 3 cm³. The excess power density and energy balance were high, 7.3 W/cm³ and −2.9×10⁴ kJ/mole H₂, respectively. This catalytic plasma reaction may represent a new hydrogen energy source and a new field of hydrogen chemistry.

The energetic catalytic reaction of hydrogen in a helium plasma was characterized by measuring the line broadening and intensity of the 656.3 nm Balmer α line to determine the excited hydrogen atom energy and H concentration and the power balance using water bath calorimetry on helium-hydrogen plasmas compared to krypton control plasmas. The catalytic plasma reaction was used to synthesize a novel amorphous silicon hydride surface coating designated α-SiH(1/p). Silane was reacted in a helium-hydrogen microwave discharge plasma at the surface of a nickel foil. After the plasma reaction processing, the surface was characterized by ToF-SIMS and XPS. Aqueous HF acid etched silicon surfaces were found to rapidly oxidized when exposed to air and provided little protection from such exposure; whereas, the novel a—SiH(1/p) identified as having high-binding-energy hydride ions was extremely stable to air. The novel α-SiH(1/p) film may advance semiconductor fabrication and devices.

Line Broadening Measurements

The widths of the 656.3 nm Balmer α and 486.1 nm Balmer β lines emitted from hydrogen, xenon-hydrogen (90/10%), or helium-hydrogen mixture (90/10%) microwave discharge plasmas were measured according to the methods given previously [21, 32]. The experimental set up comprising a microwave discharge gas cell light source is shown in FIG. 2. Each ultrapure gas alone or mixture was flowed through a half inch diameter quartz tube at 1 Torr. The gas pressure to the cell was maintained by flowing the mixture while monitoring the pressure with a 10 torr and 1000 torr MKS Baratron absolute pressure gauge. The tube was fitted with an Opthos coaxial microwave cavity (Evenson cavity). The microwave generator was an Opthos model MPG-4M generator (Frequency: 2450 MHz). The input power to the plasma was set at 40 W. The plasma emission was fiber-optically coupled through a 220F matching fiber adapter positioned 2 cm from the cell wall to a high resolution visible spectrometer with a resolution of ±0.006 nm over the spectral range 190-860 nm. The spectrometer was a Jobin Yvon Horiba 1250 M with 2400 groves/mm ion-etched holographic diffraction grating. The entrance and exit slits were set to 20 μm. The spectrometer was scanned between 485.9-486.4 nm and 655.5-657 nm using a 0.005 nm step size. The signal was recorded by a PMT with a stand alone high voltage power supply (950 V) and an acquisition controller. The data was obtained in a single accumulation with a 1 second integration time. The electron density was determined using a Langmuir probe according to the method given previously [79].

The method of Videnovic et al. [80] and Griem [81] was used to calculate the energetic hydrogen atom energies from the width of the 656.28 nm Balmer α line emitted from hydrogen and noble gas-hydrogen microwave plasmas as described previously [21, 32]. The full half-width Δλ_G of each Gaussian results from the Doppler (Δλ_D) and instrumental (Δλ_I) half-widths:

Δλ_G=√{square root over (Δλ_D²+Δλ_I²)}

where Δλ_I in our experiments was ±0.006 nm. The temperature was calculated from the Doppler half-width using the formula:

$\begin{array}{cc}{\mathrm{\Delta \lambda }}_D=7.16\times {10}^{-6}{{\lambda }_0\left(\frac{T}{\mu }\right)}^{1/2}\left(\AA \right)& \left(12\right)\end{array}$

where λ₀ is the line wavelength in Å, T is the temperature in K (1 eV=11,605 K), and μ is the molecular weight (=1 for hydrogen). In each case, the average Doppler half-width that was not appreciably changed with pressure varied by ±5% corresponding to an error in the energy of ±10%. The corresponding number densities varied by ±10%.

The method of Sultan et al. [82] was used to calculate the hydrogen atom densities from the intensities of the 656.28 nm Balmer α line emitted from hydrogen and noble gas-hydrogen microwave plasmas as described previously [21, 32]. The absolute density of n=3 was measured as given below, then the H number density for n=1 was estimated by the following equation which is in good agreement with the evolution equations of Sultan et al. [82]:

$\begin{array}{cc}\frac{\left[H\left(n=3\right)\right]}{\left[H\left(n=1\right)\right]}=\frac{g_3}{g_1}\exp \left(-\Delta E\text{/}\mathrm{kT}\right)& \left(13\right)\end{array}$

where the degeneracy g is given by g=2n² (n is the principal quantum number) and kT≈1 eV. The number densities for noble gas-hydrogen mixtures varied by ±20% depending on the pressure.

To measure the absolute intensity, the high resolution visible spectrometer and detection system were calibrated [83] with 546.08 nm, 579.96 nm, and 696.54 nm light from a Hg—Ar lamp (Ocean Optics, model HG-1) that was calibrated with a NIST certified silicon photodiode. The population density of the n=3 hydrogen excited state N₃ was determined from the absolute intensity of the Balmer α (656.28 nm) line measured using the calibrated spectrometer. The spectrometer response was determined to be approximately flat in the 400-700 nm region by ion etching and with a tungsten intensity calibrated lamp.

Calorimetry

The excess power was measured by water bath calorimetry on helium-hydrogen (90/10%) plasmas compared to krypton plasma with the same input power. The plasmas were maintained in a microwave discharge cell shown in FIG. 3. Each gas was ultrahigh pure. Each pure test gas was flowed through a half inch diameter quartz tube at 500 mTorr maintained with a noble gas or hydrogen flow rate of 10 sccm. After the calorimeter had reached a steady state, the pressure of the helium-hydrogen mixture was changed to 0.29 torr. Each gas flow was controlled by a 0-20 sccm range mass flow controller (MKS1179A21CS1BB) with a readout (MKS type 246). The cell pressure was monitored by a 0-10 Torr MKS Baratron absolute pressure gauge. The tube was fitted with an Evenson coaxial microwave cavity (Opthos) having an E-mode [84-85]. The microwave generator shown in FIG. 3 was an Opthos model MPG-4M generator (Frequency: 2450 MHz).

The Evenson cavity and a plasma-containing section of the quartz tube were fitted with a water-tight stainless steel housing shown in FIG. 3. The housing comprised a 4×4×2 cm rectangular enclosure welded to a set of high vacuum 15.24 cm diameter conflat flanges. A silver plated copper gasket was placed between a mating flange and the cell flange. The two flanges were clamped together with 10 circumferential bolts. The top mating flange contained two penetrations comprising 1.) a stainless steel thermocouple well (1 cm OD) housing a thermocouple probe in the cell interior that was in contact with the quartz tube wall adjacent to the Evenson cavity and 2.) a centered 2.54 cm OD coaxial cable housing. The 1.27 cm OD quartz tube was sealed at its penetrations with the rectangular housing by Ultratorr fittings. The housing and cell assembly was suspended by 4 support rods from an 5.1 cm thick acrylic plate which held the cell vertically from the top of a water bath calorimeter shown in FIG. 3. The plate contained four sealed penetrations comprising 1.) the stainless steel thermocouple well 2.) a 1 cm OD noble or hydrogen gas line, 3.) a 1 cm OD vacuum line, and 4.) the 2.54 cm OD coaxial cable housing. The gas inlet connected to a 0.64 cm OD flexible stainless steel tube that was connected by an Ultratorr seal to a welded-in 0.63 cm OD penetration of the rectangular enclosure. Inside of the enclosure, the penetration connected to the quartz tube by a 0.63-to-1.27 cm OD mating Ultratorr seal. The quartz tube had an elbow at the end opposite to the gas inlet penetration which attached to a 1 cm OD flexible stainless steel tube section of the vacuum line. The microwave cavity contained in the rectangular enclosure was tuned by a threaded tuning stub sealed in an end wall of the enclosure and a sliding tuning stub sealed with an Ultratorr fitting in the bottom wall. The sliding stub was tightened after the cell was tuned outside of the water bath, and the cell was immersed.

The water bath comprised an insulated reservoir filled with 45 liters of distilled water. The water was agitated with a paddle driven by a stirring motor. A high precision linear response thermistor probe (Omega OL-703) recorded the temperature of the water bath as a function of time for the stirrer alone to establish the baseline. The water bath was calibrated by a high precision heater (Watlow 125CA65A2X, with a Xantrex DC power supply 0-1200+0.01 W). The heat capacity was determined for several input powers, 30, 40, and 50 W±0.01 W, and was found to be independent of input power over this power range within ±0.05%. The temperature rise of the reservoir as a function of time gave a slope in ° C./s. This slope was baseline corrected for the negligible stirrer power and loss to ambient. The constant known input power (J/s), was divided by this slope to give the heat capacity in J/° C. Then, in general, the total power output from the cell to the reservoir was determined by multiplying the heat capacity by the rate of temperature rise (° C./s) to give J/s.

Since the cell and water bath system were adiabatic, the general form of the power balance equation is:

P _in +P _ex −P _out=0  (14)

where P_in is the microwave input power, P_ex is the excess power generated from the hydrogen catalysis reaction, and P_out is the thermal power loss from the cell to the water bath. The cell typically reached steady state in about 10 minutes after each experiment was started. At this point, the power lost from the cell P_out was equal to the power supplied to the cell, P_in, plus any excess power P_ex.

P _in +P _ex =P _out  (15)

Since the cell was surrounded by water that was contained in an insulated reservoir with negligible thermal losses, the temperature response of the thermistor T as a function of time t was modeled by a linear curve

T ^Y(t)=α⁻¹P_out  (16)

where α is the heat capacity (J/° C.) for the least square curve fit of the response to power input for the control experiments (P_ex=0). The slope was recorded for about 2 hours after the cell had reached a thermal steady state, to achieve an accuracy of ±1%.

The slope of the temperature rise as a function of time was recorded for each run and baseline corrected for the negligible stirrer power and loss to ambient, then the output power was calculated from the corrected slope. After the calorimeter was calibrated, T(t) was recorded with a selected setting of the forward and reflected power to the krypton plasma. The slope was determined with this constant forward and reflected microwave power, and the microwave input power was absolutely determined for these panel meter readings using Eq. (16) with the T^Y(t) response and the heat capacity α. Then, identical forward and reflected microwave power settings were replicated for the helium-hydrogen mixture and T(t) was again recorded. The higher slope produced with helium-hydrogen mixture, having He⁺ as a catalyst and atomic hydrogen as a reactant, compared with controls with no hydrogen and no catalyst present was representative of the excess power. In the case of the catalysis run, the total output power P_out was determined by solving Eq. (16) using the measured T^Y(t) and the heat capacity α. The excess power P_ex was determined from Eq. (15).

Exemplary Synthesis

Amorphous silicon hydride (α-SiH(1/p)) films were grown on nickel substrates by their exposure to a low pressure microwave discharge of SiH₄(2.5%)/He(96.6%)/H₂(0.9%). The experimental set up comprising a microwave discharge cell operated under flow conditions is shown in FIG. 4. The SiH₄ gas was introduced into a 1000 ml reservoir 49 by a gas/vacuum line 61 where it was mixed with premixed He(99%)/H₂(1%) to obtain the reaction mixture SiH₄(2.5%)/He(96.6%)/H₂(0.9%) by controlling the individual gas pressures. Nickel foil (5×5 mm and 0.05 mm thick, Alfa Aesar 99+%) substrates 55 were used to avoid charging during ToF-SIMS and XPS characterization. (In an alternative embodiment, the substrate 55 is oriented perpendicularly to the axis of the plasma tube 60 rather than parallel to the tube as shown in FIG. 4.) The synthesis of α-SiH was also performed on semiconductor substrates, Si and SiO₂ surfaces, by the same methods as for Ni substrates. The substrates were placed inside of a quartz tube 60 (1.3 cm in diameter by 15.5 cm long) with vacuum valves 53, 54, and 59 at both ends. The tube was fitted with an Opthos coaxial microwave cavity 56 (Evenson cavity) and connected to the gas/vacuum line 63. The quartz tube 60 and vacuum line 61, 62, 63, 64, and 65 were evacuated sufficiently to remove any trace moisture or oxygen. The gas mixture SiH₄(2.5%)/He(96.6%)/H₂(0.9%) was flowed from sources 45 and 46 through the quartz tube 60 at a total pressure of 0.7 Torr maintained with a gas flow rate of 40 sccm controlled by a mass flow controller with a readout. The cell pressure was monitored by an absolute pressure gauge 51. The microwave generator 57 shown in FIG. 4 was an Opthos model MPG-4M generator (Frequency: 2450 MHz). The microwave plasma was maintained with a 40 W (forward)/15 W (reflected) power for about 20 min. Yellow-orange coatings formed on the substrates and the wall of the quartz tube. The quartz tube was removed and transferred to a drybox with the samples inside by closing the vacuum valves at both ends and detaching the tube from the vacuum/gas line. The coated substrates were mounted on XPS and ToF-SIMS sample holders under an argon atmosphere in order to prepare samples for the corresponding analyses. One set of samples was analyzed with air exposure limited to 10 minutes and another for 20 minutes while transferring and mounting during the analyses. Separate samples were removed from the drybox and stored in air at room temperature for 48 hours or 10 days before the analyses. Controls comprised a commercial silicon wafer (Alfa Aesar 99.99%) untreated, and HF cleaned silicon wafers exposed to air for 10 minutes or 3 hours.

Characterization

a. ToF-SIMS Characterization

The commercial silicon wafer, HF cleaned silicon wafer, and α-SiH(1/p) coated nickel foil samples were characterized using Physical Electronics TRIFT ToF-SIMS instrument. The primary ion source was a pulsed ⁶⁹Ga⁺ liquid metal source operated at 15 keV [86-87]. The secondary ions were exacted by a ±3 keV (according to the mode) voltage. Three electrostatic analyzers (Triple-Focusing-Time-of-Flight) deflect them in order to compensate for the initial energy dispersion of ions of the same mass. The 400 pA dc current was pulsed at a 5 kHz repetition rate with a 7 ns pulse width. The analyzed area was 60 μm×60 μm and the mass range was 0-1000 AMU. The total ion dose was 7×10¹¹ ions/cm², ensuring static conditions. Charge compensation was performed with a pulsed electron gun operated at 20 eV electron energy. In order to remove surface contaminants and expose a fresh surface for analysis, the samples were sputter-cleaned for 30 s using a 80 μm×80 μm raster, with 600 pA current, resulting in a total ion dose of 10⁵ ions/cm². Three different regions on each sample of 60 μm×60 μm were analyzed. The positive and negative SIMS spectra were acquired. Representative post sputtering data is reported. The ToF-SIMS data were treated using ‘Cadence’ software (Physical Electronics), which calculates the mass calibration from well-defined reference peaks.

b. XPS Characterization

A series of XPS analyses were made on the samples using a Scienta 300 XPS Spectrometer. The fixed analyzer transmission mode and the sweep acquisition mode were used. The angle was 15°. The step energy in the survey scan was 0.5 eV, and the step energy in the high resolution scan was 0.15 eV. In the survey scan, the time per step was 0.4 seconds, and the number of sweeps was 4. In the high resolution scan, the time per step was 0.3 seconds, and the number of sweeps was 30. C 1s at 284.5 eV was used as the internal standard.

RESULTS AND DISCUSSION

A. Line broadening Measurements

The 656.3 nm Balmer α line width recorded with a high resolution (±0.006 nm) visible spectrometer on microwave discharge plasmas of hydrogen compared with each of xenon-hydrogen (90/10%) and helium-hydrogen (90/10%) are shown in FIGS. 5 and 6, respectively. The average helium-hydrogen Doppler half-width of 0.52±5% nm was not appreciably changed with pressure. The corresponding energy of 180-210 eV and the number density of 5×10¹⁴+20% atoms/cm³, depending on the pressure, were significant compared to only ≈3 eV and 7×10¹³ atoms/cm³ for pure hydrogen, even though 10 times more hydrogen was present. Only ≈3 eV broadening was observed with control xenon-hydrogen (90/10%) ruling out collisional broadening. The xenon-hydrogen plasma number density of 3×10¹³ atoms/cm³ was much lower than that of the helium-hydrogen plasma. Furthermore, only the hydrogen lines were broadened. The addition of hydrogen to helium had no effect on the helium lines as shown for the 667.816 nm He I line in FIG. 7.

Doppler broadening due to thermal motion was assumed to be the dominant source to the extent that other sources may be neglected. This assumption was confirmed when each source was considered. In general, the experimental profile is a convolution of a Doppler profile, an instrumental profile, the natural (lifetime) profile, Stark profiles, van der Waals profiles, a resonance profile, and fine structure. The contribution from each source was determined to be below the limit of detection [21, 26, 32].

Furthermore, no hydrogen species, H⁺, H₂⁺, H₃⁺, H⁻, H, or H₂, responds to the microwave field; rather, only the electrons respond. But, the measured electron temperature was about 1 eV; whereas, the measured H temperature was 180-210 eV. This requires that T_H>>>T_e. This result can not be explained by electron or external Stark broadening or electric field acceleration of charged species. The electron density was n_e˜10⁸ cm⁻³, at least five orders of magnitude too low [21, 26, 32] for detectable Stark broadening. And, in microwave driven plasmas, there is no high electric field in a cathode fall region (>1 kV/cm) to accelerate positive ions as proposed previously [80, 88-90] to explain significant broadening in hydrogen containing plasmas driven at high voltage electrodes. It is impossible for H or any H-containing ion which may give rise to H to have a higher temperature than the electrons in a microwave plasma. The observation of excessive Balmer line broadening in a microwave driven plasma requires a source of energy other than that provided by the electric field. The source is the catalytic reaction of atomic hydrogen with He⁺ and subsequent autocatalytic reactions of the lower-energy hydrogen product given previously [36, 41].

The formation of fast H can be explained by a resonant energy transfer from hydrogen atoms to He⁺ ions of two times the potential energy of atomic hydrogen, 2·27.2 eV, followed by a collisional energy transfer to yield fast H(n=1) as well as the emission of q·13.6 eV photons discussed previously [35-36, 41]. For example, the exothermic chemical reaction of H+H to form H₂ does not occur with the emission of a photon. Rather, the reaction requires a collision with a third body, M, to remove the bond energy-H+H+M→H₂+M* [71]. The third body distributes the energy from the exothermic reaction, and the end result is the H₂ molecule and an increase in the temperature of the system. In the case of the He⁺ catalytic reaction with the formation of states given by Eqs. (1,3), the temperature of H becomes very high.

The hydrogen atom temperature in plasmas of hydrogen mixed with helium were about 50-100 times that observed for the control plasmas such as hydrogen mixed with xenon or hydrogen alone. Even so, the observed ≈3 eV temperature of the latter plasmas was still well above the resolution capability of the instrument, and surprisingly it was appreciably above that expected based on the electron temperature of about 1 eV. The observation of an elevated hydrogen atom temperature for pure hydrogen plasmas and mixtures containing hydrogen with the unusual absence of an elevated temperature of any other gas present can be explained by a catalytic reaction involving hydrogen atoms alone. Since the ionization energy of hydrogen is 13.6 eV, two hydrogen atoms can provide a net enthalpy equal to the potential energy of the hydrogen atom, 27.2 eV—the necessary resonance energy, for a third hydrogen atom. On this basis, the unusual observation of the H energy slightly above the electron temperature is expected. The effect is expected to more pronounced with greater hydrogen concentration such as that achieved near or on the cathode in RF and glow discharge cells as described previously [21, 32].

Power Balance of the Helium-Hydrogen Microwave Plasma

The thermogram, T(t) response of the cell, with stirring only and with a constant input power to the high precision heater of 50 W is shown in FIG. 8. The baseline corrected least squares fit of the slope, T^Y(t), was 2.622×10⁻⁴° C./s, and the heat capacity determined from Eqs. (15-16) with P_ex=0, and P_in=P_out=50 W was 1.907×10⁵ J/° C. Then the temperature response of the calorimeter for any case (Eq. (16)) was determined to be

T ^Ý(t)=(1.907×10⁵J/° C.)⁻¹×P_out  (17)

The T(t) water bath response to stirring and then with selected panel meter readings of the constant forward and reflected microwave input power to krypton was recorded as shown in FIG. 9. Using the corresponding T^Y(t) in Eq. (17), the microwave input power was determined to be 8.1±1 W. A helium-hydrogen (90/10%) mixture was run at the same microwave input power readings as the control which corresponded to P_in=8.1±1 W in Eq. (15). The T(t) response was significantly increased for helium-hydrogen (90/10%) as shown in FIG. 9. At 350 minutes, the pressure was changed from 0.5 torr to 0.29 torr. A slight increase in T^Y(t) was observed at the lower pressure, possibly due to an increase in atomic hydrogen and He⁺. The excess power was determined to be 21.9±1 W from the corresponding T^Y(t) using Eq. (17) and Eq. (15).

The sources of error were the error in the calibration curve (±0.05 W) and the measured microwave input power (±1 W). The propagated error of the calibration and power measurements was ±1 W.

Given a helium-hydrogen (90/10%) flow rate of 10.0 sccm and an excess power of 21.9 W, energy balances of over −2.9×10⁴ kJ/mole H₂ (150 eV/H atom) were measured. The reaction of hydrogen to form water which releases −241.8 kJ/mole H₂ (1.48 eV/H atom) is about 100 times less than that observed. Given that no conventional chemical reaction is plausible, the results indicate that the catalytic reaction of atomic hydrogen with He⁺ and subsequent autocatalytic reactions given previously [36, 41] occur to a significant extent. This is consistent with the previously reported series of lower-energy hydrogen lines with energies of q·13.6 eV where q=1, 2, 3, 4, 6, 7, 8, 9, or 11 [35-36, 41], the previously given theory [36, 41, 68], and previous studies which show very large energy balances [2, 7, 26, 30, 3436, 38-39, 44, 46, 58, 65-67].

Characterization

a. ToF-SIMS Characterization

The positive ToF-SIMS spectra (m/e=0-100) of the noncoated cleaned commercial silicon wafer control and a nickel foil coated with an α-SiH(1/p) film and exposed to air for 10 min. are shown in FIGS. 10 and 11, respectively. The positive ion spectrum of the silicon wafer control was dominated by Si⁺, oxides Si_xO_y⁺, and hydroxides Si_x(OH)_y⁺; whereas, that of the α—SiH(1/p) sample contained essentially no oxide or hydroxide peaks. Rather, it was dominated by Si⁺ and a peak at m/z=29 which comprised a contribution from SiH⁺ and ²⁹Si⁺ which were difficult to separate definitively. However, the contribution due to SiH⁺ could be determined by calculating the ratio

$R=\frac{{\hspace{0.17em}}^{28}\mathrm{Si}}{{\hspace{0.17em}}^{28}\mathrm{SiH}+{\hspace{0.17em}}^{29}\mathrm{Si}}.$

For comparison, the theoretical ratio of

$\frac{{\hspace{0.17em}}^{28}\mathrm{Si}}{{\hspace{0.17em}}^{29}\mathrm{Si}}$

based on isotopic abundance is 19.6. R for the clean noncoated silicon wafer was 8.1. Whereas, R for the α—SiH(1/p) sample was 1.15 indicating that the m/z=29 peak was overwhelmingly due to SiH⁺.

The positive spectrum (m/e=0-100) of a nickel foil coated with an α-SiH(1/p) film and exposed to air for 10 days before the ToF-SIMS analysis is shown in FIG. 12. In this case R was 1.75 demonstrating that the sample was extraordinarily stable to air exposure. In contrast, R was 2.45 in the positive spectrum (m/e=0-100) of the HF cleaned silicon wafer exposed to air for only 10 min. before ToF-SIMS analysis as shown in FIG. 13.

The negative ion spectra (m/e=0-100) of the noncoated cleaned commercial silicon wafer and a nickel foil coated with an α-SiH(1/p) film and exposed to air for 10 min. before ToF-SIMS analysis are shown in FIGS. 14 and 15, respectively. The control spectrum was dominated by oxide (O⁻m/z=16) and hydroxide (OH⁻m/z=17); whereas, spectrum of the α-SiH(1/p) film was dominated by hydride ion (H⁻m/z=1). Very little oxide or hydroxide was observed.

The negative spectrum (m/e=0-100) of a nickel foil coated with an α-SiH(1/p) film and exposed to air for 10 days before the ToF-SIMS analysis is shown in FIG. 16. In this case, hydride ion also dominated the negative spectrum demonstrating extraordinary air stability of the a—SiH(1/p) film. The negative spectrum (m/e=0-100) of the HF cleaned silicon wafer exposed to air for only 10 min. before ToF-SIMS analysis shown in FIG. 17 also shows a dominant hydride as well as oxide, hydroxide, and some fluoride (F⁻m/z=19). However, the HF treated surface was not stable with prolonged air exposure. A dominant oxide peak was observed in the negative spectrum (m/e=0-100) of the HF cleaned silicon wafer exposed to air for only 3 hours before ToF-SIMS analysis as shown in FIG. 18. Hydride was also observed in lesser amounts and may have resulted as a fragment of the observed hydroxide. Fluoride (F⁻m/z=19) was also observed. The ToF-SIMS results from the HF treated surface is consistent with predominantly H termination of silicon dangling bonds as reported previously [75-77] that has undergone rapid oxidation to form mixed oxides such as SiOH.

These results indicate that the plasma reaction formed a highly stable hydrogenated silicon coating in the absence of fluorine observed on the HF treated surface. Remarkably, the α-SiH film was stable even after 10 days; whereas, the HF treated surface showed signs of oxidation over a 1500 times shorter time scale—10 mins. At 3 hours the HF treated surface had similarities to the control untreated silicon wafer which comprised a full oxide coating.

The plasma-reaction-formed α-SiH(1/p) is shown to comprise a more stable hydride ion than the H terminated silicon from HF treatment. Thus, the ion production efficiencies in ToF-SIMS analysis could be different making a comparison only qualitative and indicative of relative changes that occurred with timed air exposure. Since the Si 2p electron of all samples was equivalent except for energy shifts due to the presence of ordinary H, novel H, or oxide, qualitative analysis was possible as given in the XPS section. As shown in this section, the ToF-SIMS results were confirmed by XPS.

XPS Characterization

The XPS survey spectra of the noncoated cleaned commercial silicon wafer (control) and a nickel foil coated with an α-SiH film and exposed to air for 20 min were obtained over the region E_b=0 eV to 1200 eV and are shown in FIGS. 19 and 20, respectively. The survey spectra permitted the determination of all of the elements present and detected shifts in the binding energies of the Si 2p peak, which also identifies the presence or absence of SiO₂. The major species identified in the XPS spectrum of the control sample were silicon, oxygen, and carbon. The a—SiH(1/p) sample contained essentially silicon with negligible oxygen and carbon.

The XPS spectra (96-108 eV) in the region of the Si 2p peak of the noncoated cleaned commercial silicon wafer and a nickel foil coated with an α-SiH(1/p) film and exposed to air for 20 min. are shown in FIGS. 21 and 22, respectively. The XPS spectrum of the control silicon wafer shows a large SiO₂ content at 104 eV as given by Wagner et al. [91]. In contrast, the α-SiH(1/p) sample had essentially no SiO₂. In addition, spin-orbital coupling gives rise to a split Si 2p peak in pure silicon, but this peak changed to a single broad peak upon reaction to form the α-SiH(1/p) film indicative of amorphous silicon.

The XPS spectrum (96-108 eV) in the region of the Si 2p peak of a nickel foil coated with an α-SiH(1/p) film and exposed to air for 48 hours before the XPS analysis is shown in FIG. 23. Essentially no SiO₂ was observed at 104 eV demonstrating that the sample was extraordinarily stable to air exposure. Perhaps trace SiOH is present in the region of 102 eV potentially due to less than 100% coverage of the surface with the α-SiH(1/p) film; rather, some silicon deposition may have occurred. In contrast, the XPS spectrum (96-108 eV) in the region of the Si 2p peak of the HF cleaned silicon wafer exposed to air for 10 min. before XPS analysis was essentially fully covered by partial oxides SiO_x such as SiOH. The mixed silicon oxide peak in the region of 101.5-104 eV shown in FIG. 24 was essentially the same percentage of the Si 2p as that of the SiO₂ peak of the uncleaned wafer shown at 104 eV in FIG. 21. In addition, the O 1s peak of the α-SiH(1/p) film exposed to air for 48 hours shown in FIG. 25 was negligible; whereas, that of the HF cleaned wafer exposed to air for 10 min. was intense as shown in FIG. 26.

The 0-70 eV and the 0-85 eV binding energy region of high resolution XPS spectra of the commercial silicon wafer and a HF cleaned silicon wafer exposed to air for 10 min. before XPS analysis are shown in FIGS. 27 and 28, respectively. Only a large O 2s peak in the low binding energy region was observed in each case. The 0-70 eV binding energy region of a nickel foil coated with an α-SiH(1/p) film and exposed to air for 20 min. before XPS analysis is shown in FIG. 29. By comparison of the α-SiH(1/p) sample to the controls, novel XPS peaks were identified at 11, 43, and 55 eV. These peaks do not correspond to any of the primary elements, silicon, carbon, or oxygen, shown in the survey scan in FIG. 20, wherein the peaks of these elements are given by Wagner et al. [91]. Hydrogen is the only element which does not have primary element peaks; thus, it is the only candidate to produce the novel peaks and correspond to the H content of the SiH coatings. These peaks closely matched and were assigned to hydride ions, H⁻(¼), H⁻( 1/9), and H⁻( 1/11), respectively, given by Eqs (4-5). The novel hydride ions are formed by the catalytic reaction of He⁺ with atomic hydrogen and subsequent autocatalytic reactions of H(1/p) to form highly stable silicon hydride products comprising SiH(1/p) (p is an integer greater than one in Eqs. (4-5)).

The XPS spectra of the Si 2p region were analyzed, and it was found that the Si 2p peak was shifted 0.3-0.7 eV for the α-SiH(1/p) films relative to that of the HF cleaned silicon wafer as shown in FIGS. 22 and 23 compared to FIG. 21. The shift was due to the influence of the hydride ions since no other counter ion peaks were observed as shown by the survey scan, FIG. 20. The stability and the intensity of the hydride ion peaks in the low binding energy region were correlated with the shift of the Si 2p peaks as shown by the shift of 0.3 eV in FIG. 22 compared to a 0.7 eV shift in FIG. 23. This provides further evidence of a novel a—SiH(1/p) film with increased stability due to the novel hydride ions.

These results indicate that the plasma reaction formed a highly stable novel hydrogenated coating; whereas, the control comprised an oxide coating or an ordinary hydrogen terminated silicon surface which rapidly formed an oxide passivation layer. The hydrogen content of the α-SiH(1/p) coating appears to be novel hydride ions with high binding energies which account for the exceptional air stability.

CONCLUSIONS

Microwave helium-hydrogen plasmas showed extraordinary broadening, and the corresponding extremely high hydrogen-atom temperature of 180-210 eV was observed with the presence of helium ion catalyst only with hydrogen present. Using water bath calorimetry, excess power was observed from the helium-hydrogen plasma compared to control krypton plasma. For a 8.1 W input, the thermal output power of the helium-hydrogen plasma was measured to be 30.0 W corresponding to 21.9 W of excess power in 3 cm³. The excess power density and energy balance were high, 7.3 W/cm³ and −2.9×10⁴ kJ/mole H₂, respectively.

The energetic plasma reaction was used to synthesize a potentially commercially important product. Nickel substrates were coated by the reaction product of a low pressure microwave discharge plasma of SiH₄(2.5%)/He(96.6%)/H₂(0.9%). The ToF-SIMS identified the coatings as hydride by the large SiH⁺ peak in the positive spectrum and the dominant H⁻ in the negative spectrum. XPS identified the H content of the SiH coatings as hydride ions, H⁻(¼), H⁻( 1/9), and H⁻( 1/11) corresponding to peaks at 11, 43, and 55 eV, respectively. The novel hydride ions are formed by the catalytic reaction of He⁺ with atomic hydrogen and subsequent autocatalytic reactions of H(1/p) to form highly stable silicon hydride products SiH(1/p) (p is an integer greater than one in Eqs. (4-5)). The SiH coating was amorphous as indicated by the shape of the Si 2p peak and was remarkably stable to air exposure. After a 48 hour exposure to air, essentially no oxygen was observed as evidence by the negligible O 1s peak at 531 eV and absence of any SiO_x Si 2p peak in the region of 102-104 eV. The highly stable amorphous silicon hydride coating may advance the production of integrated circuits and microdevices by resisting the oxygen passivation of the surface and possibly altering the dielectric constant and band gap to increase device performance.
