摘要

The doped [(Ca0.95M0.05)(2)CoO3][CoO2](1.61) ceramics were sintered by the spark plasma sintering (SPS). The electrical conductivity, Seebeck coefficient and thermal conductivity of all samples were measured from 373 K to 973 K. The doped ions improve thermoelectric performance due to increase of Seebeck coefficient and decrease of thermal conductivity. Since the electrical resistivity of the Y-doped sample has no enhancement, the thermoelectric performance of the Y-doped sample is superior to that of the Gd-doped sample. The reason of the different effects on the thermoelectric performance comes from magnetic action.
