From picometre displacements to a three-dimensional lattice gas of polar skyrmions
Joohee Bang, Nives Strkalj, Hugo Aramberri +4
Polar skyrmions, the electric analogues of magnetic skyrmions, form arrays in PbTiO3/SrTiO3 superlattices that are known to be only short-range ordered, but how this disordered ens…
Soft-mode nonlinearities away from ferroelectric phase transition
Payel Shee, Ipek Efe, Jingwen Li +3
The interplay between ionic and electronic subsystems dictates the behavior of structural phase transitions in polar dielectrics, a coupling mediated by soft optical phonon modes.…
Polarizing ultrathin ferroelectric BaTiO3 films through interfacial layer polarization
Ipek Efe, Edith Simmen, Tobias Goldenberger +3
An important requirement for the integration of ferroelectric thin films into devices is deterministic control of the polarization state in films of only a few unit cells in thickn…
Manipulating ferroelectricity without electrical bias: A perspective
Bixin Yan, Valentine Gillioz, Ipek Efe +1
Ferroelectric materials are established candidates for beyond complementary metal-oxide-semiconductor technology, owing to their non-volatile spontaneous electrical polarization. T…
Electro-Optic Modulation in Polycrystalline Barium Titanate Metasurfaces Enhanced by Poling
Eleni Prountzou, Helena C. Weigand, Virginia Falcone +2
Electrically tunable metasurfaces leveraging the strong Pockel's effect in barium titanate (BaTiO or BTO) are a promising platform for reconfigurable free-space optical devices…
Chemical heterogeneity at conducting ferroelectric domain walls
Kasper A. Hunnestad, Guo-Dong Zhao, Mao-Hua Zhang +7
Natural interfaces in ferroic oxides have developed into versatile playgrounds for studying electronic correlation effects in 2D systems. The microscopic origin of the emergent loc…
