Electrophotographic studies of glow-discharge amorphous silicon

Abstract
Photoelectronic properties of glow-discharge amorphous silicon (a-Si) relevant to its use as a photoreceptor for electrophotography are described on the basis of the measurements of the xerographic discharge characteristics as well as conventional photoconductivity under various experimental conditions: impurity doping, temperature, and light intensity. A hole μτ product of 2–6 × 10−8 cm2/V at electric fields of 103–105 V/cm for intrinsic a-Si: H are obtained.
