Abstract
The thermostimulated conductivity, static characteristics, and kinetics of photoconductivity in undoped GaSe monocrystals with p-type conductivity are studied over the temperature range 80–350‡K. Photocurrent as a function of intensity and wavelength of exciting light, and relaxation curves are analyzed. Insignificant temperature and infrared photocurrent extinction was observed. The major parameters of photosensitive centers are determined. It is demonstrated that the experimentally observed principles of photoconductivity in gallium selenide can be explained within the framework of the two-center recombination model, as realized for many wide-zone photoconductors [1–3].
