title = "Enhancement of light extraction of GaN-based light-emitting diodes with a microstructure array",
abstract = "An optical model for simulating light extraction efficiency of a GaN-based LED chip is presented. We propose the introduction of a periodic sharpening structure on the interface between the sapphire and the n-GaN of a GaN-based LED to obtain as high as 78% light extraction efficiency.",
