title = "Extraction efficiency improvement of GaN light-emitting diode using sub-wavelength nanoimprinted patterns on sapphire substrate",
abstract = "The sapphire substrate with sub-wavelength pattern pitch (200 nm) was fabricated by nanoimprint and has significantly enhanced the extraction efficiency of GaN LED (λ=450 nm) -- 80% more light out than the LEDs on flat sapphire substrate that grown in the same run and better than previously-reported micro-scale patterns.",
