Design Simulation of Top ITO Gratings to Improve Light Transmission for Gallium Nitride LEDs
Las Vegas, NV（2009）
摘要
We present simulation results of the indium tin oxide (ITO) top diffraction grating using a rigorous couple wave analysis (RCWA) for GaN LEDs. We study three different nano-structure patterns: cylindrical pillar grating, conical pillar grating, and cylindrical nano-hole grating. We show the light transmission improvement with nano-grating designs and present design-charts for the nano-hole grating.
