- wherein the dopant is selected from the group consisting of cations of alkali metals, cations of alkaline earth metals, cations of transition metals, NH.sub.4.sup.+, PH.sub.4.sup.+, cations of metal elements belonging to groups IIb, IIIa, IVa, and Va, trihalide ions, AuI.sub.2.sup.-, AuBr.sub.2.sup.-, NO.sub.3.sup.-, BF.sub.4.sup.-, ClO.sub.4.sup.-, ReO.sub.4.sup.-, PF.sub.6.sup.-, AsF.sub.6.sup.-, Cl.H.sub.2 O, Cu(NCS).sub.2.sup.-, and Cu(N(CN).sub.2)Br.sup.- ; and
- wherein said sheath comprises copper or silver.
- 2. A process for producing a stabilized carbon cluster conducting material as claimed in claim 1, wherein said doping treatment is effected by heating said sheath filled with said mixture.
- 3. A process for producing a stabilized carbon cluster conducting material comprising the steps of: filling a sheath with a mixture comprising a carbon cluster and a dopant; and subjecting said sheath filled with said mixture to a doping treatment;
- wherein the dopant is selected from the group consisting of cations of alkali metals, cations of alkaline earth metals, cations of transition metals, NH.sup.4.sup.+, PH.sub.4.sup.+, cations of metal elements belonging to groups IIb, IIIa, IVa, and Va, trihalide ions, AuI.sub.2.sup.-, AuBr.sub.2.sup.-, NO.sub.3.sup.-, BF.sub.4.sup.-, ClO.sub.4.sup.-, ReO.sub.4.sup.-, PF.sub.6.sup.-, AsF.sub.6.sup.-, Cl.H.sub.2 O, Cu(NCS).sub.2.sup.-, and Cu(N(CN).sub.2)Br.sup.- ; and
- wherein said sheath comprises copper or silver, and said carbon cluster is C.sub.60 or a C.sub.60 /C.sub.70 mixture.
- 4. A process for producing a stabilized carbon cluster conducting material as claimed in claim 1, wherein said carbon cluster is C.sub.60 or a C.sub.60 /C.sub.70 mixture doped with at least one dopant selected from the group consisting of Group I elements, Group II elements, Group III elements, and Group IV elements.
- 5. A process for producing a stabilized carbon cluster conducting material as claimed in claim 4, wherein said dopant is selected from the group consisting of an alkali metal, an alkaline earth metal, a noble metal, In, and Sn.
- 6. A process for producing a stabilized carbon cluster conducting material as claimed in claim 5, wherein said dopant is an alkali metal.
- 7. A process for producing a stabilized carbon cluster conducting material as claimed in claim 5, wherein said dopant is Sn.
- 8. A process for producing a stabilized carbon cluster conducting material comprising the steps of: filling a sheath with a mixture comprising a carbon cluster and a dopant; subjecting said sheath filled with said mixture to a doping treatment; and pressing or wire drawing after said doping treatment;
- wherein the dopant is selected from the group consisting of cations of alkali metals, cations of alkaline earth metals, cations of transition metals, NH.sub.4.sup.+, PH.sub.4.sup.+, cations of metal elements belonging to groups IIb, IIIa, IVa, and Va, trihalide ions, AuI.sub.2.sup.-, AuBr.sub.2.sup.-, NO.sub.3.sup.-, BF.sub.4.sup.-, ClO.sub.4.sup.-, ReO.sub.4.sup.-, PF.sub.6.sup.-, AsF.sub.6.sup.-, Cl.H.sub.2 O, Cu(NCS).sub.2.sup.-, and Cu(N(CN).sub.2)Br.sup.-.
