The goal of DARPA's research program in Infrared Detector Materials is to develop a science base for production of affordable large area high performance focal plane arrays. Intrinsic materials (HgCdTe and related Hg-based alloys) are preferred, principally because of their large absorption coefficient. A summary of progress and issues in bulk and epitaxial growth of II-VI materials, II-VI superlattices, contacts, ion implantation, and low frequency noise is given.
