Published in 2023 at "IEEE Electron Device Letters"

DOI: 10.1109/led.2023.3264983

Abstract: In this study, we investigated the temperature-dependent photoluminescence characteristics of green InGaN/GaN multiple quantum wells (MQWs) with InGaN/GaN pre-wells and InGaN pre-layers, and the electroluminescence properties of the corresponding mini-LEDs were fabricated and studied. According… read more here.

DOI: 10.1364/oe.558548

Abstract: Femtosecond laser has greatly enabled the development of high-resolution, high-aspect-ratio and damage-free nano-processing. In this study, we adopted single- and multifocal femtosecond laser stealth dicing to fabricate the on-wafer GaN-based mini-LEDs grown on sapphire. Due… read more here.

Published in 2025 at "Optics letters"

DOI: 10.1364/ol.577320

Abstract: Owing to the low refractive index of conventional passivation materials and sidewall defects, AlGaInP-based red miniaturized light-emitting diodes (mini-LEDs) suffer from low light extraction efficiency (LEE) and external quantum efficiency (EQE). Here, we propose a… read more here.

Published in 2021 at "Nanomaterials"

DOI: 10.3390/nano11092395

Abstract: Mini-light-emitting diodes (mini-LEDs) were combined with multiple three-dimensional (3D) diffuse reflection cavity arrays (DRCAs) to produce thin, large-area, high-brightness, flat light source modules. The curvature of the 3D free-form DRCA was optimized to control its… read more here.
