Work on infrared detectors was started at Syracuse University in February 1948. The research has represented a continuing effort in the development and analysis of new infrared detector materials, the construction of detectors from these materials as well as measurement and analysis of the parameters of these detectors. The two most important accomplishments of the work at Syracuse University have been the development of the first liquid nitrogen cooled detector in the 3-6 micrometers range to be used in the U.S. aircraft PbTe, and the first detector in the 8-14 micrometers range which did not require liquid helium but could be operated with mechanical coolers GeHg. In addition, a great deal of progress has been made in developing test techniques, in preparing and understanding the behavior of impurities in InSb and in Ge. Most recently, p and n type impurities in silicon have been studied. Currently both HgCdTe and PbSnTe are being prepared in our laboratory and an effort is being made to prepare better and more reproducible material and to understand the behavior of both materials.
