Abstract:InGaN‐GaN quantum dots (QDs) have been grown, with variations in the deposition time used to vary the properties of the dots. Atomic force microscopy (AFM) studies of uncapped dots indicate a small increase in dot density with increasing deposition time. Photoluminescence (PL) spectroscopy at low temperatures reveals a red shift of the dot emission as the deposition time is increased. Power dependent PL measurements indicate that it is relatively easy to saturate the QD ground state emission because of their l… Show more
