      We report the high-temperature thermoelectric properties of electron- and hole-doped calcium manganese oxidematerials, which exhibit potential of a thermoelectric device for conversion of wasteful thermal energy into useful electricalenergy. Electron-doped Ca$_{0.9}$R$_{0.1}$MnO$_3$ (R $=$ La, Yb) and hole-doped Ca$_4$Mn$_{2.85}$Nb$_{0.15}$O$_{10}$ manganites chosen for the present study were prepared by solid-state reaction of starting compounds and characterized by powder X-ray diffraction. Electrical resistivity and thermopower were measured as a function of temperature to determine the power factor for all the three compounds studied. We discuss these results according to their application potential as a thermoelectric device.
