Abstract
Thermoelectricity of mixed ionic electronic conductor BaTiO3+δ is thermodynamically analyzed, and measured across the mixed n/p regime of both undoped and 1.8 m/o A1-doped BaTiO3 at elevated temperatures. There can be 4 different measurement conditions with respect to the nonstoichiometry (δ) redistribution and types of atmosphere gases used to control the surrounding oxygen potential, which lead to differences in information content of the thermopower. Experimental thermopower isotherms are exhaustively analyzed to find that the ionic contribution is evident in the mixed n/p regime and that the heats of transport of electrons and holes are about the same as their migration enthalpies.
