Abstract

The otherorhombic distorted perovskite La1−xSrxRuO3 (0.1<x<0.9) polycrystalline samples have been prepared using conventional solid state chemistry reaction. The phase constituent, compositional homogeneity and micro-morphology were checked by X-ray powder diffraction, Energy Disperse X-ray spectroscopy and scanning electron microscopy before characterized by means of the electrical resistivity, thermal conductivity and thermal power measurements. Particularly, the compositional dependence of Seebeck coefficient of present compound was studied in light of the comparison with the strongly correlated system NaxCoO4 and the relevant model proposed by W. Koshibae. Finally, the potential of using La1−xSrxRuO3 as a practical thermoelectric material has been also discussed.
