Abstract

A substantially flat body of a photoconductive semiconductor material is coated on one surface with an electrically conductive layer. A layer of a solid insulator material is on another surface of the semiconductor material. The insulator material is of the type having mobile deep lying carriers and forms a blocking junction with the semiconductor material. The insulator material may be an electronically conductive glass, an ionically conductive glass, or a cermet composition. The photoconductor can be used as a target for a camera tube, or as an electrophotographic plate.
