Conductivity and thermoelectric coefficients of doped SrTiO${}_3$ at high temperatures

Kh. G. Nazaryan, M. V. Feigelman

We developed a theory of electric and thermoelectric conductivity of lightly doped SrTiO${}_3$ in the non-degenerate region $k_{B}T\ge E_F$, assuming that the major source of electr…
