摘要：

Using electrical conductivity (sigma), Seebeck coefficient (S), thermal expansion, specific heat, and thermal diffusivity measurements in air in the temperature range 300-1200 K, we have determined the thermal conductivity (kappa), thermoelectric power factor (S-2 sigma), and thermoelectric figure of merit (ZT = S-2 sigma T/kappa) of Ca0.5-xSr0.5LuxMnO3-delta (x = 0.05, 0.10, 0.15, 0.20) manganites. The Ca0.5-xSr0.5LuxMnO3-delta material has been shown to have the highest S2 sigma and ZT owing to its high S and low kappa.
