Modulation of superconductivity by ferroelectric polarization in confined ferroelectric-superconductor-ferroelectric films [PDF]

Physical Review B, 2004
We show that the electric polarization at the interface with ultrathin superconducting (S) films sandwiched between ferroelectric (FE) layers allows achievement of substantially stronger modulation of inner carrier density and superconducting transition temperature as compared to FE-S bilayers typically used in superconducting FET's.

Recipes for improper ferroelectricity in molecular perovskites

Nature Communications, 2018
In layered inorganic materials lattice distortions can couple to break inversion symmetry and drive improper ferroelectricity, but in perovskites, symmetry prohibits such an effect.

Polar magnetic oxides from chemical ordering: A new class of multiferroics

APL Materials, 2020
Combining ferroelectricity and magnetism in the same material remains a challenge because it involves complex crystal chemistry and stringent symmetry requirements. In conventional ferroelectrics, the polarization arises from the second-order Jahn–Teller

Large Photoinduced Tuning of Ferroelectricity in Sliding Ferroelectrics

Physical Review Letters
Stacking nonpolar, monolayer materials has emerged as an effective strategy to harvest ferroelectricity in two-dimensional (2D) van de Waals (vdW) materials. At a particular stacking sequence, interlayer charge transfer allows for the generation of out-of-plane dipole components, and the polarization magnitude and direction can be altered by an ...
