Abstract

The photoelectric properties of the surface of n-type cadmium telluride single crystals of various specific resistivities were investigated by measuring illumination-induced changes of the electrode potential of the crystals in aqueous electrolytes as functions of the polarization current, the intensity of the illumination, and the spectrum of the incident light. It was established that the observed photoeffect results from electron-hole pairs generated in the surface barrier regions of cadmium telluride. A photoelectric response was not observed in the case of p-type samples.
