Abstract:
1. A vertical geometry light emitting diode capable of emitting light in the electromagnetic spectrum wherein said light emitting diode comprises: a substrate; a lift-off layer coated on said substrate comprising Al a strain relief superlattice layer on said lift-off layer wherein said strain relief superlattice layer comprises repeating periods of Al a first doped layer on said strain relief superlattice layer wherein said first doped layer comprises Al a multilayer ultraviolet emitting quantum well region on said first doped layer comprising alternating layers of: a quantum well comprising Al a barrier layer on each surface of said quantum well having a band gap larger than a quantum well bandgap and said barrier layer comprises Al a second doped layer on said quantum well region wherein said second doped layer comprises Al a contact layer on said second doped layer comprising Al a second metallic contact formed on the second doped contact layer in a vertical geometry orientation.
