| 内容記述 | Thermoelectric properties of layered oxyselenides La1–xSrxCuOSe (x = 0.00 to 0.20) were investigated to evaluate the potential as thermoelectric material. Temperature dependence of the electrical conductivity and Seebeck coefficient measured in a temperature range of 373 to 673 K indicated that nondoped LaCuOSe was a p-type degenerate semiconductor due to Cu vacancies, while Sr-doped materials with x = 0.05 to 0.20 were p-type metals. The electrical conductivity increased and Seebeck coefficient decreased with increasing Sr concentration up to x = 0.10 in La1–xSrxCuOSe, suggesting that the effective hole carriers increase with increasing Sr content up to x = 0.10. Thermoelectric power factors were drastically enhanced by the Sr doping, and the value reached 1.0–1.4×10–4 W m–1 K–2 for La0.95Sr0.05CuOSe. Thermal conductivities measured for the materials with x = 0.00 and 0.05 were 2.1 W m–1 K–1 and 2.3 W m–1 K–1 at room temperature, respectively. These results lead to an estimation of Z value of 4.4×10–5 K–1 for La0.95Sr0.05CuOSe. | |||||||||||||
