Design Simulation of Top ITO Gratings to Improve Light Transmission for Gallium Nitride LEDs
2009
2009 Sixth International Conference on Information Technology: New Generations
Preserved Fulltext
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.
