Abstract. The electrophysical properties of Sm x Pb 1-x Te (x ≤ 0.08) solid solutions have
been investigated. The electric conductivity, Hall coefficient and Hall mobility of charge
carriers in the temperature range 80 to 800 К have been measured. The mechanism of
charge carrier scattering in solid solutions has been ascertained. It is established that
increase of samarium content and simultaneous participation of interacting Sm 2+ and
Sm 3+ ions in the transfer process lead to decrease in electric conductivity. The change of
conductivity type from p- to n-type means that obtained solid solutions are partly
compensated semiconductors.
Keywords: solid solution, electric conductivity, Hall coefficient, Hall mobility,
mechanism of scattering.
