Mesa-height Dependent Quantum Efficiency Characteristics of InGaN Micro-LEDs

Abstract
The mechanisms of mesa-height dependent efficiency and efficiency droop of blue InGaN/GaN micro-LED is presented. Device with a large etch-depth (> 1.3 µm) shows significant strain relief with aggravated current crowding.
