Abstract

The grain size and the density of the Zn_{1 - x}Sn_xO (0 ≤ x ≤ 0.05) samples decreased with increasing SnO₂ content. The addition of a small amount of SnO₂ (x ≤ 0.01) to ZnO led to an increase in both the electrical conductivity and the absolute value of the Seebeck coefficient, resulting in a significant increase in the power factor. The thermoelectric power factor was maximized to a value of 1.25 × 10^-3 Wm^-1 K^-2 at 1073 K for the Zn_0.99Sn_0.01O sample.
