A vertical geometry light emitting diode is disclosed that is capable of emitting
light in the red, green, blue, violet and ultraviolet portions of the electromagnetic
spectrum. The light emitting diode includes a conductive silicon carbide substrate,
an InGaN quantum well, a conductive buffer layer between the substrate and the
quantum well, a respective undoped gallium nitride layer on each surface of the
quantum well, and ohmic contacts in a vertical geometry orientation.
