Abstract

The Hall coefficient and electrical conductivity were measured for crystals of cadmium sulfide-selenide for various sulfur-selenium ratios. From these data, the charge carrier concentrations and Hall mobilities were calculated. In addition, the variation of the optical absorption edge was determined as a function of the sulfur-selenium ratio; and the energy gap inferred. The crystals showed little photoconductive effect. In fact, it was difficult to separate the change in conductivity due to incident illumination from the ordinary majority carrier conduction.
