Abstract

Measurements of EL2 degrees and EL2(+) concentrations by IR absorption and temperature-dependent photocurrent (1.13 eV) and dark current at 80K < T < 300K in semi-insulating GaAs, allow a more accurate analysis of the thermally stimulated current spectrum. We conclude that trap T-2, at 220K, is related to As-Ga and controlled by both EL2 degrees and EL2(+), and T-3, at 200K is most likely a V-As-related defect complex..
