Spectral and Small-Signal Electroluminescence Analysis of Carrier Dynamics in Dual-Color InGaN/GaN Light-Emitting Diodes
Xuefeng Li, Rob Armitage, Daniel Feezell
We study carrier transport, distribution, and recombination in dual-color c-plane InGaN/GaN LEDs using spectral analysis and small-signal electroluminescence (SSEL). The emissions…

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…

Multiple-Carrier-Lifetime Model for Carrier Dynamics in InGaN/GaN LEDs with Non-Uniform Carrier Distribution
Xuefeng Li, Elizabeth DeJong, Rob Armitage +1
We introduce a multiple-carrier-lifetime model (MCLM) for light-emitting diodes (LEDs) with non-uniform carrier distribution, such as in multiple-quantum-well (MQW) structures. By…
