Investigation on the optical properties of Al nanograting deep-ultraviolet LEDs with rough surface of sapphire
The optical properties of Al nanograting deep ultraviolet LEDs with a rough surface of sapphire are investigated by the finite-difference time-domain simulation. The rough surface of sapphire is characterized by rms amplitude and correlation length. The calculation results indicate that the rough sa...
