ABSTRACT:
A photoconductor body for a camera tube includes a semiconductor body including an overlayer of a material selected from a granular metal-insulator system. Suitable semiconductor materials are limited to those materials capable of providing Schottky barrier heights in excess of 0.9 eV. when fabricated with such overlayers and those having bandgaps greater than about 1.4 eV. A method of fabricating such photoconductive bodies is disclosed wherein a cadmium selenide semiconductor material is thermally treated to modify the Schottky barrier heights to a desired value in excess of about 0.9 eV.
