Thallous Sulfide Photo-Conductive Cells I. Experimental Investigation

Abstract

An experimental study of thallous sulfide photo-conductive cells is presented. It includes an investigation of the sensitizing oxidation reaction; cell characteristics as function of voltage, temperature, light intensity, wave-length, modulating frequency, and composition; measurements of thermoeffect and optical absorption; x-ray and electron diffraction studies, and an examination of the photo-response to light flashes of very short duration. A theoretical discussion will be given as Part II in a subsequent paper.
