Abstract

An investigation of the photoquenching behaviour in semi-insulating GaAs at low temperature shows that the ASGa antisite MCD-ODMR is persistently quenched while a broad vacancy-like resonance near g=2, which shows a variation of g-factor with absorption energy, broadens and becomes energy independent. The results are discussed in terms of interacting antisite and vacancy centres in analogy with the distant pair model for donor-acceptor pair recombination and the advantages of the triplet model for the EL2 metastahle state are reviewed.
