Photoinduced defects creation on sulfur passivated surface of GaAs

Abstract

We report on photoinduced defect creation on the sulfurized (100) GaAs surface. The process manifests itself by unrecoverable temporal decrease in the photoluminescence intensity of the GaAs surface treated by (NH4)2Sx solution. The results are discussed in terms of a photoinduced process of the AsGa antisite generation on the sulfurized surface of GaAs.Peer Reviewe
