  • Abstract
    Ferroelectric superlattices of (LaAlO3)m/(BaTiO3)n (LAOm/BTOn) is used to investigate functional properties of ferroelectric thin films by first-principles method. We find that LAOm/BTOn system are different from the II-IV-type perovskite superlattice systems, when the LAO layer effectively affects the BTO layer lattice atomic and electronic structure. This anomalous indicates that a small period superlattices are useful for improve the ferroelectricity under compressive strain.
