Junction formation with pure and doped polyacetylene

A variety of rectifying junctions have been fabricated using doped and undoped (CH)x. Schottky diodes formed between metallic AsF5-doped (CH)x and n-type semiconductors indicate high CH(AsF5)yx electronegativity. The p-type character of undoped trans- (CH)x is confirmed by Schottky-barrier formation with low-work-function metals. An undoped p- (CH)x : n-ZnS heterojunction has been demonstrated with an open-circuit voltage of 0.8 V. These results point to the potential of (CH)x as a photosensitive material for use in solar-cell applications.
