Electric resistivity, thermal conductivity, and the thermopower of polycrystalline Sr-doped LaCoO3 with composition La 0.9Sr0.5CoO3 were measured. The crystal structure of the synthesized powders was determined by x-ray powder diffraction. The stoichiometry of the cations was found to be very close to the nominal one by energy dispersive x-ray spectroscopy measurements. The results show that these polycrystalline samples serve as a potential room-temperature p-type thermoelectric oxide for cooling applications.
