Abstract

In this paper we present a direct observation of the lateral diffusion of photogenerated carriers in InGaN/GaN quantum wells. The spatial distribution of the photoluminescence around a small exciting laser spot is analyzed by scanning in the focal plane of our confocal microscope. The results of a blue and a green emitting sample at varying excitation densities are discussed in the context of the ...
