摘要: We present investigations on the two dominating acceptor levels observed in Cu-diffused GaAs which have frequently been attributed to ionization of a double Cu Ga acceptor. employed plasma hydrogenation and lithium diffusion followed by reverse-bias zero-bias annealing passivate subsequently reactivate Cu-related levels. Deep-level current-transient spectroscopy measurements reveal that are independently reactivated, strongly indicating they arise from different defects.
