Paper Abstract

Infrared photon detectors have significant advantages over other technologies due to their fast response times and multispectral detection capabilities. However, background- limited performance is typically not achieved without significant cooling of the detectors. We discuss several strategies from improving their high-temperature performance. They are: (1) the suppression of radiative recombination using photon recycling, (2) the suppression of both radiative and Auger recombination with carrier depletion, and (3) the suppression of Auger recombination using band structure engineering in strained layer superlattices. All three effects provide significant enhancements in detectivities. We focus on extending present-day bulk HgCdTe technology to bulk and strained layer superlattice-based HgCdTe high-temperature detectors.
