As of the starting date of this contract, a variety of rectifying junctions had been fabricated using doped and undoped (CH)/sub x/. Schottky diodes formed between metallic AsF/sub 5/-doped (CH)/sub x/ and n-type semiconductors indicate high (CH(AsF/sub 5/)/sub y/)/sub x/ electronegativity. The p-type character of undoped trans-(CH)/sub x/ was confirmed by Schottky barrier formation with low work function metals. An undoped p-(CH)/sub x/:n--ZnS heterojunction solar cell has been demonstrated with open circuit photovoltage of 0.8 V. These results point to the potential of (CH)/sub x/ as a photosensitive material for use in solar cell applications. The devices fabricated in initial experiments fall into three categories: 1) Schottky diodes utilizing heavily doped (CH)/sub x/ as a metallic electrode on a variety of n-type semiconductors, 2) Schottky diodes utilizing undoped (CH)/sub x/ as a p-type semiconductor on which metallic contacts are placed, and 3) p-n heterojunction diodes formed at the inferface of undoped p-type (CH)/sub x/ on n-ZnS. Progress is reported. (WHK)
