Abstract

Thermoelectric properties of Sr-doped LaCoO₃ system such as La_1-xSr_xCoO₃ and La_0.95-xSr_x□_0.05CoO₃ (□: A-site vacancy) were investigated. The effects of A-site vacancy on electrical conductivity, Seebeck coefficient, and thermal conductivity were discussed. It was found that the thermoelectric properties of La_0.95-xSr_x□_0.05CoO₃ containing the A-site vacancy showed the higher values than those of La_1-xSr_xCoO₃ at 873K.
