Nitride LEDs based on Flat and 'Wrinkled' Quantum Wells

摘要

In this paper we propose a new type of nitride LED structure based on "wrinkled" rather than flat Multiple Quantum Wells (MQWs) grown along the polar [0001] direction. We show that this novel approach of employing "wrinkled" MQWs leads to the improvement of both the internal quantum efficiency as well the extraction efficiency.
