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.

In-Situ measurements of the relative thermal resistance: Highly sensitive method to detect crack propagation in solder joints
TL;DR: In this article, the authors used transient thermal analysis to detect the crack propagation in solder joints by measuring the relative thermal resistance using high power ceramic LED packages, which can be applied on high power devices which have to dissipate a significant amount of thermal load through the solder joint.

Phantom array and stroboscopic effects of a time-modulated moving light source during saccadic eye movement:
TL;DR: Evaluating the detectability of the phantom array and stroboscopic effects during light source motion, eye movement and their combination, using time modulated light-emitting diode light sources indicates that one of the most important factors for the Stroboscopic-phantom array effect is eye movement speed relative to the speed of the light source.
