On the efficiency droop of top-down etched InGaN/GaN nanorod light emitting diodes under optical pumping

The optical performance of top-down etched InGaN/GaN nanorod light emitting diodes (LEDs) was studied using temperature variable photoluminescence spectroscopy with a 405 nm pump laser. Efficiency droop is measured from such nanorod structures, which is further enhanced with decreasing temperature....
