The control of the in-plane domain evolution in ferroelectric thin films is not only critical to understanding ferroelectric phenomena but also to enabling functional device fabrication. However, in-plane polarized ferroelectric thin films typically exhibit complicated multi-domain states, not desirable for optoelectronic device performance. Here we report a strategy combining interfacial symmetry engineering and anisotropic strain to design single-domain, in-plane polarized ferroelectric… Expand

Polar-Graded Multiferroic SrMnO3 Thin Films.
This work explores the existence of a polar-graded state in epitaxially strained antiferromagnetic SrMnO3 thin films, whose polar nature was predicted theoretically and recently demonstrated experimentally, and presents a chemistry-mediated route to induce polar rotation in oxygen-deficient multiferroic films, resulting in flexoelectric polar rotations and with potentially enhanced piezoelectricsity.

Effect of symmetry mismatch on the domain structure of rhombohedral BiFeO3 thin films
Considerable work has focused on the use of epitaxial strain to engineer domain structures in ferroic materials. Here, we revisit the observed reduction of domain variants in rhombohedral BiFeO3Expand

The control of a bulk property, namely ferroelectric polarization, of a heteroepitaxial bilayer by precise atomic-scale interface engineering is demonstrated by exploiting the interfacial valence mismatch to influence the electrostatic potential step across the interface. Expand
Effect of substrate constraint on the stability and evolution of ferroelectric domain structures in thin films
The stability and evolution of ferroelectric domain structures in thin films are studied. Elastic solutions are derived for both elastically anisotropic and isotropic thin films with arbitrary domainExpand
Imprint Control of BaTiO3 Thin Films via Chemically Induced Surface Polarization Pinning.
The studies based on synchrotron X-ray scattering and coherent Bragg rod analysis demonstrate that the chemically induced surface polarization is not switchable but reduces the polarization imprint and improves the bistability of ferroelectric phase in BTO tunnel junctions. Expand
Long‐Range Domain Structure and Symmetry Engineering by Interfacial Oxygen Octahedral Coupling at Heterostructure Interface
In epitaxial thin film systems, the crystal structure and its symmetry deviate from the bulk counterpart due to various mechanisms such as epitaxial strain and interfacial structural coupling, whichExpand
Controlled lateral anisotropy in correlated manganite heterostructures by interface-engineered oxygen octahedral coupling.
Here, it is demonstrated how to manipulate magnetic and electronic anisotropic properties in manganite heterostructures by engineering the oxygen network on the unit-cell level by atomic-scale design of the oxygen octahedral rotation. Expand

Induced ferroelectricity in strained epitaxial SrTiO3 films on various substrates
The impact of strain on structure and ferroelectric properties of epitaxial SrTiO3 films on various substrate materials—substrates with larger (DyScO3) and smaller (NdGaO3 and CeO2/Al2O3) in-planeExpand
Room-temperature ferroelectricity in strained SrTiO3
It is shown that epitaxial strain from a newly developed substrate can be harnessed to increase Tc by hundreds of degrees and produce room-temperature ferro electricity in strontium titanate, a material that is not normally ferroelectric at any temperature. Expand
