Identification and Mitigation of Droop Mechanism in GaN-Based LEDs

Lead Performer: University of California - Santa Barbara – Santa Barbara, CA
DOE Total Funding: $1,000,001
Cost Share: $250,000
Project Term: July 1, 2015 – June 30, 2018
Funding Opportunity: SSL R&D Funding Opportunity Announcement (FOA) (DE-FOA-0001171)

Project Objective

This project will focus on identifying the fundamental causes of current droop in state-of-the-art commercial LEDs. An electroemission spectroscopy tool will be developed to identify the dominant electrical and thermal droop mechanisms and then to optimize non-polar and semi-polar LEDs, obtain conclusive determination of the origin of the green gap, and assess the origin of thermal droop.
