Abstract: The results of studying the temperature dependences of electrical conductivity, thermoelectric coefficient, Hall mobility of charge carriers, total and electronic thermal conductivity, as well as the phonon thermal resistance of alloys of solid solutions (CuInSe$_2$)$_{1-x}$(In$_2$Te$_3$)$_x$, where $x$ = 0.005 and 0.0075. The values of these parameters for certain temperatures were used to calculate the values of the thermoelectric figure of merit of the indicated compositions. It turned out that with an increase in temperature, the thermoelectric figure of merit tends to grow strongly, which is why it can be concluded that these materials can be used in the manufacture of thermoelements.

Keywords: solid solutions, scattering mechanisms, three-phonon processes, thermoelectric efficiency.
