Abstract

Blue InGaN LED suffers from a severe efficiency droop at high current density and electron leakage is believed to be one of the primary causes of it. In this study, InGaN LED was simulated using Sentaurus TCAD. The effects of thickness of the quantum wells on the device performances were examined through simulation. Results of the simulations suggested that to achieve a low efficiency droop, the wells have to be thick.
