Effect of Surface Texture on Light Extraction Efficiency for LEDs
Crystals, 2023 The light extraction efficiency of an LED is dependent on its surface texture. However, the surface of the p-GaN layer is not easy to be etch with inverted hexagonal pyramid structures (IHPS) with small top widths and large depths using existing methods.

Enhancing the Light Extraction Efficiency in Micro‐Organic Light‐Emitting Diodes with Metalens
Advanced Photonics Research, 2021 Due to the total internal reflection caused by the mismatch of the refractive indices between organic layers and oxide layers within an organic light‐emitting diode (OLED), most of the light energy is trapped inside the device; if the size of an OLED is ...
