Simple method for accurately determining the injection efficiency and bulk quantum efficiency of light-emitting diodes
C. van Opdorp,L. Blok +1 more
TL;DR: In this paper, the external quantum efficiency of a homojunction or single-heterojunction LED can be expressed as η inj · η bulk, i.e. the product of the injection efficiency of minority carriers to the light-generating side of the junction, and the external bulk quantum efficiency with which these carriers recombine there.

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.
