Abstract
In this work we investigate indium dose dependence of optical properties of quantum dot fabricated by droplet epitaxy. Photoluminescence measurements demonstrate red shift to 1.3 µm and considerable change of a dot spectra form with peak number increase. The Gaussians decomposition analysis revealed some characteristic peak widths corresponded to different QD groups. One width is close to Stranski-Krastanov growth mode value, measured on our analogical samples. It indicates that since some indium amount there is transition of droplet to SK growth mode.
