Development on improving extraction efficiency of GaN LEDs by surface roughing technique of wet etching
碩士 === 國立臺灣師範大學 === 機電科技研究所 === 95 === Light extraction efficiency is always a problem for GaN LED. And surface roughing is simple and useful technology for raising light extraction efficiency. Because of GaN with high refraction coefficient (n=2.5), by Snell’s law, it can create a critical angle of...
