Investigation on Improving Light Output of Light Emitting Diodes with Porous Anodic Alumina
碩士 === 國立成功大學 === 微電子工程研究所碩博士班 === 95 === Recently, the external quantum efficiency of light emitting diodes (LEDs) is poor due to the high refractive index of semiconductor. Many researches reported various methods to improve the light extraction efficiency. In this thesis, we used porous anodic al...
