Overshoot effects of electron on efficiency droop in InGaN/GaN MQW light-emitting diodes
2016
To evaluate electron leakage in InGaN/GaN multiple quantum well(MQW)light emitting diodes(LEDs), analytic models of ballistic and quasi-ballistic transport are developed. With this model, the impact of critical variables effecting electron leakage, including the electron blocking layer (EBL), structure of multiple quantum wells(MQWs),polarization field, and temperature are explored. The simulated results based on this model shed light on previously reported experimental observations and provide basic criteria for suppressing electron leakage, advancing the design of InGaN/GaN LEDs.
