Electron-doped perovskite Ca 1− x Bi x MnO 3 (x = 0, 0.02, 0.03, 0.04, 0.06 and 0.10) was prepared by a conventional solid-state reaction method. Their homogeneity was confirmed using X-ray diffraction and their thermoelectric properties were measured up to 973 K.The results indicate that both the electrical resistivity and the absolute value of the Seebeck …
