Patent ID: 8460959

Claim:
A method of forming a GaN light-emitting diode (LED), comprising: forming atop a substrate a GaN multilayer structure having a n-GaN layer and a p-GaN layer that sandwich an active layer, wherein the p-GaN layer has a dopant activation; performing fast thermal annealing of the p-GaN layer, wherein the fast thermal annealing has a time duration of about 10 seconds or faster, in order to increase the dopant activation; forming a transparent conducting layer atop the GaN multilayer structure; and adding a p-contact to the transparent conducting layer and a n-contact to the n-GaN layer wherein the n-contact has a n-contact resistance, the n-contact resistance being in the range from about 1×10 −4 ohm-cm 2 to about 1×10 −6 ohm-cm 2 .
