Strain-induced room-temperature ferroelectricity in SrTiO3 membranes [PDF]

Nature Communications, 2020
Advances in complex oxide heteroepitaxy have highlighted the enormous potential of utilizing strain engineering via lattice mismatch to control ferroelectricity in thin-film heterostructures. This approach, however, lacks the ability to produce large and

Evolution of crystallographic structure and ferroelectricity of Hf0.5Zr0.5O2 films with different deposition rate

AIP Advances, 2020
Hf0.5Zr0.5O2 films are one of the most attractive HfO2-based ferroelectric films because of good ferroelectricity, extreme thinness, and excellent compatibility with silicon devices.

Visualizing moiré ferroelectricity via plasmons and nano-photocurrent in graphene/twisted-WSe2 structures

Nature Communications, 2023
Ferroelectricity, a spontaneous and reversible electric polarization, is found in certain classes of van der Waals (vdW) materials. The discovery of ferroelectricity in twisted vdW layers provides new opportunities to engineer spatially dependent ...

Ferroelectric properties of charge-ordered alpha-(BEDT-TTF)2I3 [PDF]

, 2015
A detailed investigation of the out-of-plane electrical properties of charge-ordered alpha-(BEDT-TTF)2I3 provides clear evidence for ferroelectricity. Similar to multiferroic alpha-(BEDT-TTF)2Cu[N(CN)2]Cl, the polar order in this material is ascribed to ...

Direct transition from a disordered to a multiferroic phase on a triangular lattice [PDF]

, 2007
Competing interactions and geometric frustration provide favourable conditions for exotic states of matter. Such competition often causes multiple phase transitions as a function of temperature and can lead to magnetic structures that break inversion ...

Scale-free ferroelectricity induced by flat phonon bands in HfO2

Science, 2020
The atomic-scale structure of hafnium oxide explains ferroelectric properties for very thin films. Switching to the atomic scale Ferroelectric materials are attractive because they provide a way to change electrical resistance by using an electric field.
