Аннотация

The photoconductivity spectra of PbSnTe(In) epitaxial films are investigated by Fourier spectroscopy in the far infrared range at temperatures from 4.2 to 32.4 K. In addition to interband transitions, subgap features associated with the excitation of impurity-defect states are found in the spectra. The evolution of the spectra with temperature and additional illumination is traced.
