  • Photoconductor of cadmium selenide and aluminum oxide
    Patent number: 3947717
    Abstract: A low dark current photoconductive body includes an aluminum oxide overlayer on a cadmium selenide base layer. A transition region is provided at the interface region between the base layer and the overlayer and consists of a graded transition of cadmium and selenium with increasing amounts of aluminum and oxygen. An alternative body is disclosed omitting the overlayer. A blocking contact is provided within a portion of the body including the overlayer and/or the transition region.
