Abstract

The grain size and density of the sintered (Zn_{1 - x}Al_xO)_mIn₂O₃ bodies decreased with the small Al₂O₃ content (≤ 0.012), and then increased gradually by further increasing the Al₂O₃ content. The addition of Al for Zn in the (ZnO)_mIn₂O₃ led to an increase in both the electrical conductivity and the absolute value of the Seebeck coefficient. This indicates that the power factor was significantly enhanced by adding Al for Zn. The thermoelectric power factor was maximized to 1.67 × 10^{- 3} W m^{- 1} K^{- 2} at 1073 K for the (Zn_0.992Al_0.008O)_mIn₂O₃ sample.
