Abstract EN
We reported the SiO2 nanopillars on microscale roughened surface on GaN-based LED to enhance light-extraction efficiency.
ZnO nanoparticles were deposited on SiO2 as an etching mask before ICP etching SiO2 by successive ionic layer adsorption and reaction method (SILAR), and the different heights of SiO2 nanopillars on microroughened ITO/GaN were obtained after etching.
Compared to a regular (flat surface) GaN-based LED, the light output power for a LED with microroughening was increased by 33%.
Furthermore, the proposed LEDs with SiO2 nanopillars on microroughened surface show the enhancement in light output power by 42.7%–49.1% at 20 mA.
The increase in light output power is mostly attributed to reduction in Fresnel reflection by rough surface.
The height of SiO2 nanopillars was increasing cause resulting in more rough on the microscale surface of GaN-based LEDs.
