Abstract:
We have studied the photoconductivity spectrum, thermally stimulated current, current–light characteristics, and temperaturedependent photocurrent in Bridgmangrown orderedvacancy Ga2Se3 crystals. The observed temperature quenching of photoconductivity and two regions of its thermal activation in Ga2Se3 crystals are interpreted in terms of a multicenter recombination model which incorporates an schannel of active recombination, rcenters of photosensitivity, and traps for nonequilibrium majority carriers.
