Interfacial enhancement of ferroelectricity in CaTiO3/BaTiO3 superlattices

We carry out first-principles calculations for CaTiO3/BaTiO3superlattices with epitaxial strain corresponding to growth on a SrTiO3 substrate, and consider octahedral rotations as well as ferroelectric distortions. The calculations are done as a function of electric displacement field, and both a macroscopic and a local electrostatic analysis are carried out. We find that strong octahedral rota...

Structural Response of BaTiO3/CaTiO3 Superlattice to Applied Electric Fields

The structural response of a ferroelectric BaTiO3/dielectric CaTiO3 superlattice to the bipolar applied electric field was studied using time-resolved x-ray microdiffraction. Structural results were compared to the polarization-electric field hysteresis curve obtained from electrical measurements. The superlattice x-ray reflections were found to have a broad distribution of intensity in recipro...
