Demonstration of Multi-Active Region P-down Green LEDs with High Quantum Efficiency
Sheikh Ifatur Rahman, Robert Armitage, Siddharth Rajan
Longer wavelength emitters such as green LEDs display a pronounced efficiency drop at higher current densities, resulting in relatively low wall-plug efficiency. Multi-active regio…
Simulation of GaN-Based Light Emitting Diodes Incorporating Composition Fluctuation Effects
Sheikh Ifatur Rahman, Zane Jamal-Eddine, Zhanbo Xia +3
III-Nitride light emitting diodes (LEDs) are widely used in a range of high efficiency lighting and display applications, which have enabled significant energy savings in the last…
Origin of the injection-dependent emission blueshift and linewidth broadening of III-nitride light-emitting diodes
Nick Pant, Xuefeng Li, Elizabeth DeJong +3
III-nitride light-emitting diodes (LEDs) exhibit an injection-dependent emission blueshift and linewidth broadening that is severely detrimental to their color purity. Using first-…
Cathodoluminescence as an Effective Probe of Carrier Transport and Deep Level Defects in Droop-Mitigating InGaN/GaN Quantum Well Heterostructures
Zhibo Zhao, Akshay Singh, Jordan Chesin +7
Commercial InGaN/GaN light emitting diode heterostructures continue to suffer from efficiency droop at high current densities. Droop mitigation strategies target Auger recombinatio…
