A Study of Light Extraction and Light Pattern by Using Surface Micro-Grating of Thin - GaN Light Emitting Diode
碩士 === 國立中央大學 === 光電科學研究所 === 97 === Because the low heat conductivity of sapphire substrate, so GaN - based light emitting diodes are inappropriate for high - power injection. In this thesis, we applied different line - width of grating structure on u - GaN surface, and to discuss the influence of...
