Highly efficient yellow photoluminescence from {11–22} InGaN multiquantum-well grown on nanoscale pyramid structure
TL;DR: In this paper, temperature dependent photoluminescence (PL) measurements from 10 to 300 K showed a high integrated intensity ratio of 0.45, and the emission energy of the MQW monotonically decreases with temperature increase, showing the absence of localized potential.

Extensive Analysis of the Degradation of Blu-Ray Laser Diodes
Matteo Meneghini,Gaudenzio Meneghesso,Nicola Trivellin,Enrico Zanoni,Kenji Orita,Masaaki Yuri,Daisuke Ueda +6 more
TL;DR: In this article, the degradation process is found to be electrothermally activated and is ascribed to the increase of the nonradiative recombination rate in the active layer, with subsequent decrease of the efficiency of the devices.

A Single-Stage Single-Switch Soft-Switching Power-Factor-Correction LED Driver
TL;DR: In this paper, a single-stage single-switch soft-switching power-factor-correction (S6-PFC) driver without electrolytic capacitors was proposed for supplying light-emitting diodes (LEDs).

Green-Light Nanocolumn Light Emitting Diodes With Triangular-Lattice Uniform Arrays of InGaN-Based Nanocolumns
Katsumi Kishino,Koji Yamano +1 more
TL;DR: In this article, a triangular-lattice uniform array of InGaN-based nanocolumns with lattice constants of 245-350 nm were fabricated with TiO2 mask selective-area growth by RF-plasma-assisted molecular beam epitaxy.
Journal ArticleDOI
LED brightness control for video display application
TL;DR: The technique is suggested for a kind of pulse-width-modulation LED dimming in LED video displays where the significant increase of the gray levels number and image refresh frequency can be achieved when the large number of LEDs is controlled serially.

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.
