Abstract
The intermetallic compounds which are mainly used for the thermoelectric power generation system are unstable at high temperature. Therefore, we studied thermoelectric property of ZnO doped with group 13 elements, which can be expected to be a good candidate of thermoelectric material with high performance. The electrical conductivity (σ) and Seebeck coefficient (S) were evaluated under He atmosphere from 673 K to 1073 K. Power factor (S2σ) of Zn9.993Ga0.0023In0.0047O showed higher value than that of Zn9.993A0.007O (A = Ga, In). Thus, the multi cation-doping was effective for the improvement of power factor.
