Deep levels in AgGaSe2
Abstract
The photoluminescence spectra of AgGaSe2 obtained at 77 K is reported. Two emission peaks have been observed and their pressure dependence studied. One of these peaks has been identified with emission involving one of the two deep level peak D(sub 1) and D(sub 2) observed previously in absorption measurement (App. Phys. Lett. 64,1717 (1994)). A simple model for the capture of carriers into these deep levels has been proposed.
