Abstract
Polycrystalline Cd1−xBaxO (0 ≤ x ≤ 0.08) ceramics were synthesized via conventional solid‐state reaction method, and the effect of Ba2+ doping on the microstructure as well as the thermoelectric transport properties of the samples were investigated. It was found that doping of Ba2+ can inhibit the grain growth of CdO, resulting in a considerable reduction in grain size. Moreover, with the increase in Ba2+ doping content, both the electrical conductivity and the thermal conductivity of Cd1−xBaxO decreased, whereas the Seebeck coefficient increased. A high ZT value of 0.47 was achieved for Cd0.99Ba0.01O at 1000 K, 38% higher than the undoped CdO, mostly due to reduction of the thermal conductivity.
