Abstract
The light extraction efficiency of GaN/InGaN based blue LED is improved by using hexagonal facets on n- and p- free surfaces and on substrate interfaces. Light interaction with patterned surfaces having hexagonal facets significantly improved the light extraction efficiency. The simulated results show that the light extraction efficiency is drastically improved from 18.08% to 89.27% by patterning the free surfaces.
