Science & Technology

An In0.21Ga0.79N epilayer has been studied by using spatially-resolved photoluminescence spectroscopy and Auger electron spectroscopy. The photoluminescence intensity is shown to be distributed highly inhomogeneously, while the epilayer also exhibits strong defect-related emission. It is shown that laser annealing at high enough power densities causes redistribution of indium atoms and results in suppression of the defect-related emission. (C) 2012 WILEY-VCH Verlag GmbH & Co.
