Soft-mode nonlinearities away from ferroelectric phase transition
Payel Shee, Ipek Efe, Jingwen Li +3
The paper investigates how electronic polarizability and local-field effects influence the soft optical phonon mode in paraelectric SrTiO₃, using linear and two‑dimensional teraher…
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…
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…
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…
Control of polarization and polar chiral textures in BiFeO by epitaxial strain and interfacial chemistry
Elzbieta Gradauskaite, Natascha Gray, Quintin N. Meier +2
The balance between interfacial chemistry, electrostatics, and epitaxial strain plays a crucial role in stabilizing polarization in ferroelectric thin films. Here, we bring these c…
