Improvement of GaN based LEDs by using concave nano patterned sapphire substrate
碩士 === 國立成功大學 === 微電子工程研究所碩博士班 === 101 === The technique of nitride-based light emitting diodes (LEDs) has been developed for many years. And nitride-based LEDs have become the most promising candidate for solid state lighting in the future. However, the external quantum efficiency is not sufficient...
