抄録

Thermoelectric power factor and figure of merit of Nd_2-xCe_xCuO₄ (x=0-0.1) sintered bodies were estimated from the Seebeck coefficient, electrical resistivity, and thermal conductivity measured in temperature range of 300-673 K. Temperature dependence of Seebeck coefficient and electrical resistivity showed n-type semiconducting behavior. Thermal conductivities, which decreased with increasing temperature for each Cc concentration, were in range of 3.7-7.5 Wm^-1K^-1. The power factor and the figure of merit for x=0.01 and 0.05 increased with decreasing temperature. Their maxima were 9.2⋅10^-5 Wm^-1K^-2 and 1.7⋅10^-5K^-1, respectively, at 320 K for x=0.05. The figure of merit would be improved to some extent by reduction of lattice thermal conductivity.
