Abstract

Defect models involving the concentration of defects as a function of p(O2) are derived for undoped BaTiO3 as well as for its solid solutions with both acceptors and donors. The basic assumption in deriving the defect models was that the Schottky-type defects are the predominant defects within p-type regime rather than acceptor-type impurities, The derived diagrams indicate that in order to decide between the conflicting models it is important to determine defect-related properties of BaTiO3 at p(O2) higher than 1 atm.
