Photoconductivity and Crystal Imperfections in Cadmium Sulfide Crystals. Part I. Effect of Impurities

Abstract
The conductivity and photosensitivity of cadmium sulfide crystals can be controlled by the incorporation of suitable impurities. The conductivity and photosensitivity are increased by the incorporation of a halide or a trivalent cation, and decreased by the incorporation of copper or silver. A possible mechanism by which such impurities may produce the observed effects on the photoconductivity is presented.
