Abstract(in English) | Fabrication processes of a moth-eye patterned sapphire substrate (MPSS), which can enhance a light extraction efficiency of nitride-based light emitting diodes (LEDs) have been examined. Optimization of structural parameters of MPSS for high-quality GaN growth was also performed. Then, we fabricated MPSS samples with a fixed pitch 460nm, and a height of corns of 250, 300 and 350nm. Light extraption efficiency of blue-LEDs growth on a series of MPSS was enhanced 1.4 times as compared with the devices grown on a flat sapphire substrate, while there is no dependence of height of corns on LED performance. |
