N2 - 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 EF and related semiconducting properties in both oxygen excess and oxygen deficit regimes at elevated temperatures at which direct experimental determination of EF 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.
