Influence of Ba2+ doping on the thermoelectric properties of BiCuSeO fabricated by spark plasma sintering

Abstract
Abstract We studied the influence of Ba2+ doping on the thermoelectric properties of the p-type Bi1–xBaxCuSeO (0 ≤ x ≤ 0.21) fabricated by spark plasma sintering. The substitution of Ba2+ for Bi3+ gradually increased the electrical and thermal conductivities and decreased the Seebeck coefficient, which were due to the increased hole concentration. The largest value of dimensionless figure-of-merit (0.57) was obtained for the Bi0.86Ba0.14CuSeO at 500 °C, which was over three times greater than that of pristine BiCuSeO (0.18) at 500 °C. We believe that the thermoelectric properties of BiCuSeO were substantially enhanced through the partial substitution of Ba2+ for Bi3+.
