Explanation of low efficiency droop in semipolar $(20\bar{2}\bar{1})$ InGaN/GaN LEDs through evaluation of carrier recombination coefficients

Morteza Monavarian, Arman Rashidi, Andrew A. Aragon +4

We report the carrier dynamics and recombination coefficients in single-quantum-well semipolar $(20\bar{2}\bar{1})$ InGaN/GaN light-emitting diodes emitting at 440 nm with 93% peak i…
