Origin of efficiency droop in GaN-based light-emitting diodes
Min-Ho Kim,Martin F. Schubert,Qi Dai,Jong Kyu Kim,E. Fred Schubert,Joachim Piprek,Yongjo Park +6 more
TL;DR: In this paper, the efficiency droop in GaInN∕GaN multiple-quantum well (MQW) light-emitting diodes was investigated and it was shown that the droop is not related to MQW efficiency but rather to the recombination of carriers outside the MqW region.
