Abstract

The electronic structure, its investigation by magneto-optical investigations and the infrared photoconductive properties of doping superlattices of PbTe are reviewed. Detectivity values of 1011 cm He1/2 W-1 are obtained at the peak wavelength of 5.8 μm at 90 K, which is close to the theoretical limit. The high quantum efficiency can be attributed to a lifetime enhancement due to the indirect energy gap in real space. The influence of blocking contacts is discussed.
