description: The temperature (1.5 K &lt;Â TÂ &lt; 300 K) and magnetic fieldÂ HÂ &lt; 5 T dependences of the electrical resistivity have been studied in bulk polycrystalline samples of semiconductor solid solutions (PbzSn1-z)0.8In0.2Te with various Pb content 0.1 â¤Â zÂ â¤ 0.9. In materials with z â¤ 0.5, when a temperature decreases, transition to the superconducting state is detected in the helium temperature region, depending on the presence of lead. It this samples the critical transition temperature reaches Tc = 4.1 K (z = 0.5). An exponential increase of the resistivity was observed in samples (PbzSn1-z)0.8In0.2Te withÂ zÂ â¥ 0.5 in the temperature range 40 K &lt;Â TÂ &lt; 120 K.Â The results are interpreted within the framework of the shift of the energy position of the indium impurity band EIn in the complex band spectrum of (PbzSn1-z)0.8In0.2Te with a change in the lead content. It has been suggested that an exponential increase in the resistance of a solid solution with decreasing temperature is observed when an energy barrier Ea appears between the states of the valence band and the impurity band of quasi-local states of indium.
