We have investigated the annealing-induced improved electrical properties of In(10 nm)/ ITO(200 nm) contacts with p-type GaN. The contacts become ohmic with a specific contact resistance of 2.75 Γ 10 -3 O cm 2 upon annealing at 650
## Abstract Waferβscale UV nanoimprint and dry etching processes were used to fabricate photonic crystal patterns on an indium tin oxide (ITO) top electrode of GaNβbased green lightβemitting diodes (LEDs). Photonic crystal patterns with pitches ranging from 600 to 900βnm were transferred to the ent
