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.

Photobiomodulation of wound healing via visible and infrared laser irradiation
TL;DR: It is observed that 635 nm laser irradiations of low energy densities had stimulative effects in terms of cell proliferation in vitro and mechanical strength of incisions in vivo, however, 809 nm Laser irradiation at the same doses did not have any positive effect.

Monolithic Inorganic ZnO/GaN Semiconductors Heterojunction White Light-Emitting Diodes
TL;DR: In this paper, a monolithic white LED was developed based on ZnO/GaN semiconductor heterojunctions, which can generate white color at the one-chip level without the wavelength conversion through packaged phosphors or chip integration for photon recycling.
