Abstract:
1. A semiconductor light emitting diode comprising: a semiconductor active structure for providing an optical emission when current is injected therethrough; an epitaxial layer of a Group III nitride that includes a top surface, a bottom surface and a side edge on a top surface of said active structure, wherein said epitaxial layer includes a p-type central region and a highly resistive Group III nitride border region that surrounds said p-type central region of the epitaxial layer for electrically isolating said p-type central region of the epitaxial layer; and a contact layer on the top surface of the epitaxial layer that defines the p-type central region of the epitaxial layer while exposing the highly resistive Group III nitride border region of the epitaxial layer, wherein the highly resistive Group III nitride border region extends to the side edge of the epitaxial layer.
