摘要：

Photoconductivity, absorption and temperature dependence of conductivity were studied in CdTe:Fe crystals. The position of the Fe2+/3+ donor level has been determined. It lies 130-150 meV above the top of the valence band. The value of the optical ionization energy has been confirmed as 1455 meV. The lattice relaxation energy has been found to be below 20 meV. The Auger photoconductivity originated by the 5E to 5T2 intracentre transitions within the Fe2+ centres has been observed.
