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.

Anisotropic transport properties of quantum dot arrays fabricated by the edge-defined nanowires
TL;DR: The anisotropic transport properties of quantum dot arrays fabricated by the nanoimprinted multilayer quantum wires revealed that lateral quantum conductance can be minimized when the Fermi level is kept at the center of the miniband gap when the gap is larger than 4kT.
Fibre optic distributed corrosion sensor
TL;DR: In this article, an ideal distributed sensing system for corrosion detection in optical fiber is presented. But the authors focus on the measurement of changes in absorption and reflection of the optical fiber.
