Abstract

Lead-salt photoconductive detectors, such as PbSe, are significant because they can operate at room temperature, be grown on silicon, be grown with low infrastructure costs, and still achieve sensitivity that is sufficient for many military and commercial applications in the MWIR. In this article we demonstrate the progress to date that we have made in our efforts to commercialize this technology for MWIR focal-plane arrays (FPAs). The potential for PbSe is to achieve a broad-band D∗ of 1×1010 cm√Hz/W a t 3 00 K a nd 1 ×1011 cm√Hz/W at 240 K surpassing the high temperature performance of both HgCdTe and SLS detectors. We discuss the challenges remaining to achieving those numbers.
