Patent ID: RE42007

Claim:
A vertical geometry light emitting diode that is capable of emitting light in the electromagnetic spectrum, said light emitting diode comprising: a conductive silicon carbide substrate; an InGaN quantum well; a conductive buffer layer between said substrate and said quantum well; a respective first undoped gallium nitride layer on each a first surface of said quantum well; a second layer consisting of undoped gallium nitride on a second surface of said quantum well opposite said first surface; and ohmic contacts in a vertical geometry orientation; a doped layer of gallium nitride between said buffer and said undoped gallium nitride layer; an undoped layer of aluminum gallium nitride on the surface of said second undoped gallium nitride layer on said quantum well that is opposite from said substrate and buffer ; and a doped layer of aluminum gallium nitride on said undoped aluminum gallium nitride layer.
