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.

Degradation of InGaN-Based Laser Diodes Related to Nonradiative Recombination
Matteo Meneghini,Nicola Trivellin,Kenji Orita,Shinichi Takigawa,Masaaki Yuri,Tsuyoshi Tanaka,Daisuke Ueda,Enrico Zanoni,Gaudenzio Meneghesso +8 more
TL;DR: In this paper, the degradation of InGaN-based laser diodes submitted to electrical stress tests was analyzed by means of optical techniques, which indicated that stress determines an increase in the threshold current of the devices without strong modifications in the slope efficiency.
