Enhancement of external quantum efficiency for GaN-based blue light emitting diodes on patterned sapphire substrate
碩士 === 國立交通大學 === 光電工程系所 === 94 === In this thesis, we employed patterned sapphire substrate (PSS) to fabricate two kinds of light emitting diodes (LEDs), V-shape sapphire facet reflector LEDs and chemical wet-etched patterned sapphire substrate(CWE-PSS) LEDs. In the first part, GaN-based LEDs with...
