Abstract

The effect of electron irradiation on CuInS2 single-crystals grown using traveling heater method has been examined using photoluminescence (PL). It has been found that the emission intensities for exciton and donor-acceptor pair transitions decrease, and that the appearance of the structures in deep PL band increases. The peaks which appeared after the electron irradiation appear to be due to the recombination emission, involving deep donors and deep acceptors.
