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.

The Influence of Physical Illumination on Lightness Perception in Simultaneous Contrast Displays.
TL;DR: The authors' results demonstrated an illumination effect on both lightness matching and perceived SLC contrast: as the intensity of illumination increased, the target on the black background appeared lighter, while the targetOn the white background was little affected.
