Abstract: The thermoelectric properties of Ca3-xYbxCo3.95Ga0.05O9+delta where x = 0.00, 0.02, 0.05, and 0.10 were determined at temperatures less than 300 K. It was determined that the partial substitution of Yb3+ for Ca2+ resulted in an increase in resistivity and thermopower. The thermal conductivity was found to decrease with increasing Yb3+ content, and the sample producing the highest thermoelectric figure of merit at 300 K was the x = 0.05 sample.
