Abstract

The experimental results of resistivity and thermoelectric power (TEP) of two YBa2Cu3O7-delta/PrBa2Cu3O7-delta (YBCO/PrBCO) superlattice samples with different thickness of YBCO layers in the temperature rangefrom 80 to 270 K are reported. The contribution of interface scattering to the resistivity of YBCO layers is estimated. Compared with slightly oxygen-deficient YBCO films, the TEP of superlattice samples has higher positive value and the slope of the linearly temperature-dependent part changes from negative to positive. A TEP peak just above T(c) was also observed.
