Abstract

The influence of specific chemical dopants on the electrophotographic behavior of selenium and its alloys has been established in prior work. This communication describes a chemical procedure that has been found effective in removing electronically active impurities from amorphous selenium. The methodology involves converting contaminated selenium into a chemical intermediate that is separated by selective alcoholic dissolution and then reduced to high-purity selenium. The electrical characteristics of the amorphous films obtained by vacuum evaporation of the latter are determined directly from analysis of xerographic potentials.
