Effects of strain on carrier recombination in GaN quantum dots


Conference Paper

Strain-induced modification of recombination dynamics in single layer (SQDs) and stacked (MQDs) GaN quantum dots is compared by time-resolved photoluminescence spectroscopy. Large strain induced built-in fields increases the radiative recombination time in SQDs by over an order of magnitude while stacking significantly reduces nonradiative recombination channels and increases the emission efficiency at room temperature.
