## Abstract We have investigated possible degradation mechanism for patterned sapphire substrate (PSS)βbased blue lightβemitting diodes (LEDs) using an acceleration burnβin test under high current stress. Normal LEDs without a PSS had also been compared. Measurements showed that the PSSβLED has low
The degradation of smooth SiGe epitaxial layer was investigated by transmission electron microscopy (TEM), X-ray reflectivity (XRR) and atomic force microscopy (AFM). It was shown from AFM results that the crosshatch was formed with increasing annealing temperature, which indicated the degradation o
