A-Plane±0.2o Patterned Sapphire Substrates BOW≤-8~0μM Back Surface Roughness 0.8~1.2μm
2inch Patterned Sapphire Substrates,LED Chip,Substrate Material
The regular patterns created on the sapphire substrate counteracts the effect of the total internal reflection at the GaN/sapphire interface. And, the enhancement in the internal quantum efficiency benefits from the reduction of threading dislocations by possible lateral growth of GaN epilayer on the patterned sapphire substrate.
