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.

About bond model of S-type negative differential resistance in GaP LEDs
G. Gaydar,O.V. Konoreva,Ye. Maliy,Ya. М. Olikh,I. Petrenko,M.B. Pinkovska,O. I. Radkevych,V.P. Tartachnyk +7 more
TL;DR: In this paper, a possible mechanism of negative differential resistance appearing in current-voltage characteristics is proposed, based on the features of the gallium phosphide complex band structure, and the bond models are presented that explain the S-type anomaly of GaP LEDs' electrical characteristics at temperatures ≥ 120 K.
