Finally, as for the constituent electrical-and thermal-transport properties, comparison with the literature suggests the predicted ZT from the present calculations are very reasonable. Ref. investigated 20% La-doped CaTiO 3 with an estimated n ≈ 2.0 × 10 20 cm -3 and obtained a ZT of ≈ 0.1 at T = 300 K and 0.4 at T = 1100 K. n = 2.5 × 10 20 cm -3 and T = 300 K, we predict a smaller ZT = 0.0375, while at the higher T = 1100 K we predict a similar ZT = 0.448. We ascribe the discrepancy at low temperature to the likely impact of the doping on reducing the κ latt . Ref investigated 8% Pm doping in SrTiO 3 and obtained a ZT of 0.638 at 1200 K. While the authors do not quote a carrier concentration, we obtain and a similar ZT = 0.678 at a "ballpark" n = 5.0 × 10 20 cm -3 . We were unfortunately not able to find ZT values for ntype BaTiO 3 for comparison.
