Impact of Quantum Well Thickness on Efficiency Loss in InGaN/GaN LEDs: Challenges for Thin-Well Designs
Xuefeng Li, Nick Pant, Sheikh Ifatur Rahman +4
We investigate the impact of quantum well (QW) thickness on efficiency loss in c-plane InGaN/GaN LEDs using a small-signal electroluminescence (SSEL) technique. Multiple mechanisms…

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-…
