Investigation on Hybrid Green Light-Emitting Diode

Part of the Environmental Science and Engineering book series (ESE)

Abstract

We propose a hybrid light-emitting diode (LED) design comprising of p-GaN/ p-MgZnO/ InGaN/ n-MgZnO/ n-ZnO emanating green electroluminescence centered around 560 nm. We compare the performance of proposed LED with ZnO and GaN based green LEDs through 2-D numerical simulation. It is found that hybrid LED shows highest IQE of 93.2 % with added advantage of least efficiency droop at high injection current.
