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.

Red InGaP light-emitting diodes epitaxially grown on engineered Ge-on-Si substrates
Bing Wang,Cong Wang,Kwang Hong Lee,Shuyu Bao,Kenneth Eng Kian Lee,Chuan Seng Tan,Soon Fatt Yoon,Eugene A. Fitzgerald,Jurgen Michel +8 more
TL;DR: In this article, the epitaxial growth of red InGaP light emitting materials on engineered Ge-on-Si substrates was studied, and a GaAs buffer layer and lattice-matched In-GaP LEDs were grown on the Ge-On-Si sequentially in the same MOCVD process and red LEDs were demonstrated.

The influence of acoustic-dislocation interaction on intensity of the bound exciton recombination in initial and irradiated GaAsP LEDs structures
TL;DR: In this paper, the acoustic-excitant interaction of GaAsP light emitting diodes (initial and irradiated by 2.MeV electrons) was studied and the possible reason of observed changes concerning nonequilibrium dislocation clusters were discussed.

Practicable Method for Estimating Thermal Depths from Phonon-Broadened Photoexcitation Cross-Section Bands I. Foundations
TL;DR: In this paper, a trap-independent MP absorption versus emission probability relation following from analytical expressions for the limiting case of vanishing phonon dispersion is generalized to arbitrary dispersion of phonon energies assumed, however, to remain unchanged during a transition.

Efficient Carrier Injection, Transport, Relaxation, and Recombination Associated with a Stronger Carrier Localization and a Low Polarization Effect of Nonpolar m-plane InGaN/GaN Light-Emitting Diodes
TL;DR: Based on time-resolved electroluminescence (TREL) measurement, more efficient carrier injection, transport, relaxation, and recombination associated with a stronger carrier localization and a low polarization effect in a nonpolar InGaN/GaN light emitting diode (m-LED), compared with those in a polar c-LED are reported.
