Description

We study the lateral diffusion of photogenerated carriers within InGaN/GaN quantum wells by scanning in the focal plane of our confocal microscope. The photoluminescence (PL) images are analyzed at varying excitation densities in the temperature range between 4 K and room temperature. The results of a blue and a green emitting sample are discussed in context of reported diffusion lengths for InGaN/GaN quantum wells. (copyright 2007 WILEY-VCH Verlag GmbH and Co.
