Abstract
Sensor Electronic Technology, Inc. proposes to use QD-like fluctuations of InGaN QW with controllable spatial distribution for high efficiency green LEDs. We will investigate both theoretically and experimentally the performance of green InGaN MQW structures with fluctuations of composition and thickness of InGaN quantum wells. Both types of these fluctuations would lead to the spatial localization of electrons (and holes) thereby reducing their in-plane diffusion to non-radiative recombination cites. We propose to use our proprietary MEMOCVD epitaxial process for growth of high quality InGaN layers with controllable distribution of fluctuations.
