ABSTRACT:
A process for preparing arsenic-selenium photoreceptors wherein the arsenic distribution in the photoreceptor, particularly at its top surface, is controlled within a preferred concentration range, which comprises controlling the evaporation rate of the arsenic-selenium alloy by means of a crucible weight sensing system to monitor alloy depletion rate and a cascade dual-loop feedback control system processing both crucible assembly weight change and temperature to modify resistive power input.
