The temperature dependence of the electrical conductivity σ , the Hall coefficient R and the thermopower coefficient α in the solid solutions TlIn_{1-x}Yb_xTe₂ (0 ≤ x ≤0.10) have been investigated in the temperature range of 80-1000 K. The effective masses of electrons and holes have been determined on the basis of the kinetic parameters. It was established that starting from x = 0.05 the solid solutions of TlIn_{1-x}Yb_xTe₂ belong to narrow-gap semiconductors having high values of the interaction matrix element. It is shown that the samples of TlIn_{1-x}Yb_xTe₂ in the region of 0.10 ≥ x ≥ 0.05 are promising materials for the energy converters operating at high temperatures.
