Efficiency enhancement of GaN based FC-LEDs by surface roughness and geometric sapphire shaping structure
碩士 === 國立交通大學 === 光電工程系所 === 95 === In the thesis, we report the flip-chip light-emitting diodes (FC-LEDs) with micro-pillar-array structure and the FC-LEDs with geometric oblique sapphire structure. In the first part, the micro pillar arrays structure is formed on the bottom side of sapphire substr...
