Single Crystal Alloy Film Infrared Detectors.
Abstract
Activation techniques have been developed to produce enhanced performance and increased yield of PbS0.5 Se0.5 detectors with large area (2/2.3 x 10 to the minus two cm) for detection of infrared (ir) radiation in the 3 micrometers to 5 micrometers band. Incorporation of chloride at the Pb salt surface and/or heat treatment annealing of the detector have been effective in enhancing device performance. The heat treatment technique which produces a diffused Pb salt/Pb interface has given the best results in terms of performance and yield. These results do not preclude the necessity of obtaining high quality epitaxial Pb salt thin films as the basis for detector fabrication. (Author)
