Abstract: The thermoelectric properties of the co-doped misfit-layered cobaltites of Ca3-x­AgxCo3.95Fe­0.05O9+delta (x=0.0, 0.1, 0.2, 0.3) were investigated at temperatures between 300 and 700 K. It was found that the thermopower increased with increasing temperature. The thermal conductivity was found to increase with increasing Ag+ content in the samples, and the highest calculated figure of merit was determined for the Ca2.8Ag0.2Co3.95Fe0.05O9+delta.
