Optical studies of non-linear absorption in single InGaN/GaN quantum dots
Nficro-photoluminescence properties of single InGaN/GaN quantum dots (QDs) are investigated using sub-bandgap excitation by 1 ps pulses from a Ti:sapphire laser. This results in almost complete suppression of background emission arising from the underlying quantum well to which the QDs are coupled....
