The efficiency droop phenomenon is a big problem for high-brightness white LEDs. It has been pointed out that the problem could be solved by the reduction of threading dislocation density in underlying GaN films (templates or substrates). Nano-channel facet-initiated epitaxial lateral overgrowth (nano-FIELO) technique has been developed as a low-cost fabrication method of such high-quality GaN templates. In this study, we have proposed that the SiO2 mask structures used for selective growth in the nano-FIELO GaN templates can also be useful for improving light extraction efficiency of LEDs, and we demonstratively optimized the mask structures (period, width, and thickness) by electromagnetic-field analysis simulation. |
