- Abstract
The thermoelectric properties, such as the Seebeck coefficient value, S, electrical conductivity, σ, and thermal conductivity, κ, of Sb- and Cu-doped SnO, that is, (SnCuSb)O, were investigated in detail. The addition of a small amount of CuO significantly improved the relative density of the SnO ceramics. However, the relative density slightly decreased with the excessive addition of CuO (more than x = 0.03). The addition of SbO should cause an increase in the number of charge carriers, resulting in an increased σ value, and the addition of both CuO and SbO caused an increase in σ and | S| at high temperature. The improvement of the sintering performance caused the enhancement of the thermoelectric performance. As the temperature region measured in this study (293-1073 K), the maximum ZT value was 0.29 at 1073 K for (SnCuSb)O.
