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.
