eng Thermoelectric Figure of Merit of Single Crystals p-(BixSb(1-x))2-ySnyTe3 in Wide Temperature Range Here we report the influence of tin doping on the thermoelectric properties of p-(BixSb(1-x))2-ySnyTe3 single crystals (x = 0; 0,25; 0,5) in the temperature range 7 K - 300 K. Studies of the temperature dependence of Seebeck coefficient S, electrical conductivity, heat conductivity k and figure of merit of p-(BixSb(1-x))2-ySnyTe3 single crystals were carried out. In order to determine the concentration of light holes and the Fermi energy, we used the Shubnikov-de-Haas effect at T = 4.2 K. By increasing the Sn content, the hole concentration increases in p-(BixSb(1-x))2-ySnyTe3. The thermal conductivity k of the p-(BixSb(1-x))2-ySnyTe3 crystals decreases due to Sn doping, while electrical resistivity increases in the temperature interval 150 K less T less 300 K and decreases at T less 150 K. The Seebeck coefficient S for all compositions is positive and decreases due to Sn doping in the whole temperature range. The main reason for this is an acceptor effect and increase of the hole concentration under Sn doping. Fermi energy increases with Sn-doping and hence Seebeck coefficient decreases.
