A comparative study of the electronic structures of BaTiO3, SrTiO3, and PbTiO3 perovskite oxides is performed in order to identify the atomistic factors governing the occurrence of a ferroelectric or antiferrodistortive (rotating-type) phase transiti

The critical thickness for ferroelectricity of a BaTiO3 film was determined by the first-principles discrete variational-Xα molecular orbital method and population analysis. Under the assumption that most ferroelectric perovskite oxides are predomin
