dc.description.abstractA short-period (BaTiO3)6/(SrTiO3)5(BaTiO3)6∕(SrTiO3)5 superlattice was characterized by x-ray diffraction and transmission electron microscopy. The superlattice is epitaxially oriented with the cc axes of BaTiO3BaTiO3 and SrTiO3SrTiO3 normal to the (001) surface of the SrTiO3SrTiO3 substrate. Despite the large in-plane lattice mismatch between BaTiO3BaTiO3 and SrTiO3SrTiO3 ( ∼ 2.2%)(∼2.2%), the superlattice interfaces were found to be nearly commensurate. The crystallographic c/ac∕a ratio of the superlattice was measured and the results agree quantitatively with first-principles calculations and phase-field modeling. The agreement supports the validity of the enhanced spontaneous polarization predicted for short-period BaTiO3/SrTiO3BaTiO3∕SrTiO3 superlattices.en_US
