Abstract

A model describing the relationship between non-stoichiometry of (La,Sr)MnO₃ (LSM), its Fermi energy level was derived. This model may be applied for the determination of the effect of p(O₂) on the changes of E_F and related semiconducting properties in both oxygen excess and oxygen deficit regimes at elevated temperatures at which direct experimental determination of E_F is difficult. The model derived for the oxygen deficit regime of LSM may also be applicable for both (La,Sr)CoO₃ and (La,Sr)FeO₃. This model may also be used for evaluation of semiconducting properties of perovskite-type oxide materials from non-stoichiometry data corresponding to the gas-solid equilibrium.
