Abstract
Deep-level transient spectroscopy has been employed for monitoring gro wn-in point defects in vapour phase epitaxial GaAs0.6P0.4:Te and GaP:N ,S. It is shown that the concentrations of deep electron traps T 1 (0. 20 eV) and T2 (0.18 eV) in GaAs0.6P0.4:Te are dependent on the shallow donor concentration and these traps are tentatively identified as Te( As)Ga(As)Te(As) and 0(i)Te(As) complexes respectively. The concentrati ons of 0.24 eV and 0.44 eV electron traps detected in GaP:N,S are depe ndent on the growth temperature and these traps are attributed to P va cancies and the ((N(P))2V(Ga))-complex respectively.
