Abstract

We have measured and analyzed the photoluminescence spectra from InGaN/GaN multiple quantum wells. Emission peaks due to recombination of the photogenerated carriers occupying localized states and extended states within quantum wells have been identified through temperature-dependent photoluminescence. Fast and slow decays have been attributed to recombination of carriers in extended states and localized states, respectively, based on time-resolved pump-probe differential photoluminescence.
