Kurzfassung
Doping of lead telluride and related alloys with group III impurities results in appearance of unique physical features of the material, such as persistent photo response, enhanced responsive quantum efficiency (up to 100), radiation hardness and many others. We review the physical principles of operation of the photo detecting devices based on the group III-doped IV-VI, including possibilities of fast quenching of the persistent photo response, construction of a focal-plane array, new readout technique, and others. Comparison of the performance of state-of-the art Ge:Ga and Si:Sb photodetectors with their lead telluride-based analogs shows that the responsivity of PbSnTe(In) photodetectors is by several orders of magnitude higher. High photoresponse is detected at a wavelength of 116 µm in PbSnTe(In), and it is possible that the photoconductivity spectrum covers all the submillimeter wavelength range.
