Optical and microstructural studies of InGaN/GaN quantum dot ensembles
Optional Fields
An optical and structural study of InGaN/GaN quantum dots (QDs) is reported. With increasing InGaN deposition time, the dominant emission changes from wetting layer (WL) to QDs, and a strong redshift of the emission occurs. Emission from localized WL states is observed, with a density and nature very different to that due to the QDs. Structural measurements reveal a disordered WL, consistent with the form of the WL photoluminescence excitation spectra. (C) 2009 American Institute of Physics. [doi:10.1063/1.3226645]
