Paper Abstract

Amorphous silicon (a-Si) alloy semiconductors are becoming increasingly important in electrophotographic applications. Photoreceptor devices based on these materials exhibit improved performance for many applications and photocopiers and laser printers using these devices are now in commercial production. Fundamental differences in the chemistry and physics of a-Si alloys, as compared to the more conventionally used amorphous chalcogenide alloys, result in differences in the way electrophotographic devices are fabricated and used. This paper will review the construction and operation of a-Si alloy photoreceptors contrasting them with amorphous chalcogenide alloy devices with particular emphasis on aspects which result from fundamental differences in the physics and chemistry of these two classes of amorphous semiconductors.
