Abstract
An improved electrophotographic photoreceptor includes a blocking layer formed from a doped, microcrystalline semiconductor alloy. The blocking layer is adapted to cooperate with the photoconductive layer of the photoreceptor to prevent the injection of undesirable charge carriers into the bulk of the photoconductive layer. Also disclosed are methods for the fabrication of the improved photoreceptor.
