Abstract
A one-step process, method and corresponding xerographic photoreceptor obtained thereby, having all or part of the hole generating layer in the trigonal form, the process being effected and the photoreceptor obtained through the use of a glow discharge and ionizable inert gas.
Claims8
A method for controlling the amount of crystalline photoconductive selenium or selenium alloy material initially applied to a xerographic base or substrate comprising exposing the base or substrate, as a cathode, to a vapor cloud comprising uncharged photoconductive material plus oppositely charged high energy photoconductive material and inert gaseous ions;
- the vapor cloud being obtained essentially by vaporizing selenium or selenium alloy in a vacuum coater in convenient proximity to a glow discharge in the presence of an inert ion-forming gas and thereafter exposing the base or substrate to an un-ionized vapor cloud at least initially comprising selenium and at least .3% by weight arsenic.
