Resumo
The thermal conductivity of CuGaTe2 and CuInTe2 was measured at high temperatures (300–800 K). The potential mechanisms of heat transport are analyzed. The total thermal conductivity of the examined compounds in the studied temperature range is completely determined by the thermal conductivity of the crystal lattice λlat. It is demonstrated that the thermal conductivity of the crystal lattice changes with temperature faster than with λlat ∼ Т–1. The potential causes of the deviation of the thermal conductivity of the crystal lattice from the Eucken law are considered.
