Enhancing the Performance of Micro LEDs via Lightweight Atomic Charge-Matching Passivation (Advanced Optical Materials 24/2025)
Micro LEDs
In article 10.1002/202500796, Weifang Lu, Jinchai Li, Kai Huang, and co-workers demonstrate a hydrogen plasma passivation technique applied after wet etching to effectively neutralize sidewall defects caused by dangling bonds and oxygen impurities in GaN-based Micro LEDs. The approach significantly enhances photoluminescence, suppresses leakage currents, and mitigates size-dependent efficiency degradations, offering a scalable strategy for improving Micro LED performance in advanced display technologies.
