Enhanced IR Detector ("nBn") Technology

Abstract

This effort investigates and improves a new barrier detector structure that makes midwave IR FPAs easier and more affordable to manufacture and allows operation at higher temperatures resulting in much more affordable sensor systems and also significant reductions in SWaP of system optics, housings and cryogenic coolers. In addition the barrier detector approach allows for very small pixel pitch (8 micron) enabling FPAs of very large format, 5000x5000 pixel, for persistent surveillance applications that were not possible prior to emergence of this barrier FPA technology. This effort contributes to the U.S. ability to ensure its historical night vision advantage.
