Congratulations to Dennis Norton for successfully defending his PhD dissertation on "Type-II InAs/GaSb Superlattice LEDs: Applications for Infrared Scene Projector Systems."

"Dennis’ research has focused on the study of novel InAs/GaSb superlattices for high-power mid-infrared (3-5 micron wavelength) light-emitting diodes and the application of such devices to large-format LED arrays designed for infrared scene projectors. In pursuing his research, Dennis collaborated with scientists and engineers at the University of Delaware, Teledyne Scientific & Imaging in California, Advanced Thermal and Environmental Concepts in Maryland, and Eglin AFB in Florida. Dennis’ research allowed him to develop skills in semiconductor device processing and testing and to build expertise in the technology associated with test and evaluation of advanced infrared focal-plane arrays. Dennis is lead author on a recently published article in IEEE Journal of Quantum Electronics detailing the design, fabrication, and characterization of the first large format (512x512 individually addressable emitters on a 48-micron pitch) mid-infrared LED array. Dennis will be conducting research, in association with Dr. Rhoe A. Thompson of Eglin AFB, focused on advancing infrared optoelectronics based on solid-state emitter sources for use in infrared scene projector systems and point-to-point communication systems."
— Thomas Boggess, PhD advisor

Dennis has received a National Research Council (NRC) Research Associate position sponsored by the Air Force Research Laboratory/Munitions Directorate in Eglin AFB, Florida.
