초록

The sidewall passivation is essential to achieve high micro lightemitting diode (LED) efficiency. We investigated different sidewall passivation strategies on InGaN/GaN blue nLED, including Thermal ALD and PEALD Al2O3. The characterization of temperature and laser excitation-dependent photoluminescence (PL) and time-resolved photoluminescence (TRPL) were observed to determine the efficiency. Sidewall passivated-nLED device was fabricated and characterized. The device exhibits extremely high brightness, even at low operation current. © 2024, John Wiley and Sons Inc. All rights reserved.
