Claims
- 1. A device comprising:a substrate comprising a fluorinated surface; and an organic semiconductor film deposited on the substrate, the film formed from a organic semiconductor compound, wherein the film comprises a continuous area greater than 1 cm2 that exhibits a charge carrier mobility of at least about 10−4 cm2V−1s−1 at room temperature.
- 2. The device of claim 1, wherein the continuous area exhibits an on/off ratio of at least 5.
- 3. The device of claim 1, wherein the continuous area greater than 1 cm2 exhibits a charge carrier mobility of at least about 5×10−3 cm2V−1s−1 at room temperature.
- 4. The device of claim 1, wherein the fluorinated surface comprises a fluorinated silane.
- 5. The device of claim 4, wherein the substrate further comprises a polymeric material underlying the fluorinated surface.
- 6. The device of claim 1, wherein the organic semiconductor compound is selected from α,ω-dihexyl-α-sexithiophene, α,ω-dihexyl-α-quinquethiophene, α,ω-bis(3-butoxypropyl)-α-sexithiophene, and naphthalene 1,4,5,8 tetracarboxylic acid diimides.
- 7. The device of claim 1, wherein the film comprises a continuous area greater than 2 cm2 that exhibits a charge carrier mobility of at least about 10−4 cm2V−1s−1 at room temperature.
- 8. The device of claim 1, wherein 80% of the continuous area exhibits a charge carrier mobility within a factor of two of the average charge carrier mobility of the continuous area.
