Patent ID: 8409972

Claim:
A light emitting diode comprising: a Group III nitride transition layer having a thickness of between about 0.3 and 1.0 microns and a dopant concentration less than 1E17 cm −3 ; an n-type Group III nitride doped layer directly on said Group III nitride transition layer; a first ohmic contact that extends from the n-type Group III nitride doped layer through an opening in the Group III nitride transition layer; at least one active layer on said Group III nitride doped layer opposite to the Group III nitride transition layer; a p-type Group III nitride layer on said at least one active layer opposite to the Group III nitride doped layer configured to generate light emission when current is applied across said p-type Group III nitride and said n-type Group III nitride doped layer; and a second ohmic contact that extends from the p-type Group III nitride layer, wherein the first and second ohmic contacts are used to apply the current across said p-type Group III nitride layer and said n-type Group III nitride doped layer.
