Figure 6.
Temperature-dependent electric charge transport properties of the as-prepared LSTO ceramic samples; experimental data are represented by solid symbols. (a) Seebeck coefficient and (b) electrical conductivity; solid lines are from the model, using the parameters listed in Table 1; the simulated curves well capture the evolution of electrical conductivity with temperature. (c) Power factor and (d) weighted mobility; the weighted mobility of single-crystal La-doped SrTiO3 calculated from the literature data32 is included for comparison purposes.
