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.

Enhancement of light extraction efficiency of InGaN quantum well light-emitting diodes with polydimethylsiloxane concave microstructures
TL;DR: In this article, the size effect of the concave microstructures on the light extraction efficiency of III-Nitride LEDs was studied, and it was shown that the use of concave arrays can lead to an increase in light extraction of InGaN LEDs by 1.4 to 1.9 times.
