Description
Sm2-xCexCuO4 (SCCO) thin films (x = 0 - 0.10) were deposited on MgO (100) and SrTiO3 (100) substrates by pulsed laser deposition method. From the x-ray diffraction (XRD) patterns, the SCCO thin films on the SrTiO3(STO) substrate were confirmed that c-axis was parallel to the substrate normal and in-plane alignment was cube-on-cube for the substrate. The Seebeck coefficient and the resistivity decreased with the increasing an amount of Ce4+ substitution. We calculated the power factor from these values and found that the highest value of 1.14 mW/mK2 at 323 K was achieved by the SCCO thin film with x = 0.02. So, as a result of repeated measurements of the thermoelectric properties in the high temperature more than 700 K, the high stability of the SCCO thin films was confirmed.
