Targets for use in photoconductive image pickup tubes |
摘要 |
The target comprises a transparent substrate, an N-type transparent conductive film formed on the substrate, a P-type photoconductive film formed on the N-type conductive film and a heterojunction formed at the interface between the N- and P-type films. The P-type photoconductive film contains selenium, tellurium and arsenic of which selenium and arsenic are distributed continuously from the heterojunction throughout the thickness of the P-type photoconductive film whereas the distribution of tellurium is spaced from the heterojunction and localized in the vicinity of the heterojunction. The total amount of arsenic contained in the P-type photoconductive film ranges from 2.5 to 6% by weight.
