Abstract: La2-xSrxCuO4(LSCO) and Sm2-xCexCuO4(SCCO) polycrystal bulks with x = 0 ∼ 0.10 were made by solid-phase reaction method. From the X-ray diffraction (XRD) patterns, LSCO and SCCO were confirmed single phase. Seebeck coefficient, resistivity and heat conductivity decreased with increasing an amount of Sr2+ and Ce4+ substitution. We estimated ZT from these values and found that the highest value of ZT = 0.034 at 323 K was achieved in the LSCO with x= 0.02. As a result, we conclude that LSCO and SCCO showed high thermoelectric properties around room temperature. We can expect RE2-xMxCuO4 is very useful material for thermoelectric module operating at room temperature.
