Room-temperature ferroelectricity in MoTe2 down to the atomic monolayer limit

Nature Communications, 2019
It is difficult to maintain ferroelectricity in the two dimensional limit. Here, the authors report robust room-temperature ferroelectricity in the thinnest monolayer MoTe2 due to relative atomic displacements of Mo and Te atoms.

Edge polarization topology integrated with sliding ferroelectricity in Moiré system

Nature Communications
Van der Waals moiré heterostructure have been found to exhibits a robust interfacial ferroelectricity down to atomic thickness, and discovering and understanding the complex polarization state in moiré systems is of fundamental interest to condensed ...

Origin of Ferroelectricity in Orthorhombic LuFeO$_3$

, 2019
We demonstrate that small but finite ferroelectric polarization ($\sim$0.01 $\mu$C/cm$^2$) emerges in orthorhombic LuFeO$_3$ ($Pnma$) at $T_N$ ($\sim$600 K) because of commensurate (k = 0) and collinear magnetic structure.

Endowing Ferroelectric Properties of Tetragonal Lysozyme Crystals through C₆₀ Doping

Crystals
The inherent nonpolarity of tetragonal lysozyme crystals excludes a ferroelectricity response. Herein, we present a demonstration of achieving measurable ferroelectricity in tetragonal lysozyme crystals through C60 doping. Ferroelectric characterizations

Direct Epitaxial Growth of Polar Hf_0.5Zr_0.5O₂ Films on Corundum

Nanomaterials, 2022
Single-phase epitaxial Hf0.5Zr0.5O2 films with non-centrosymmetric orthorhombic structure have been grown directly on electrode-free corundum (α-Al2O3) substrates by pulsed laser deposition.

Investigation on structural, dielectric and ferroelectric properties of samarium-substituted BiFeO3–PbTiO3 composites [PDF]

Journal of Advanced Dielectrics, 2017
The polycrystalline samples of 0.8BiSmxFe1−xO3–0.2PbTiO3 (x=0.05,0.10,0.15 and 0.20) were prepared by using the conventional solid-state reaction technique and sintered at high temperature (850∘C).

Room temperature ferroelectricity in monolayer graphene sandwiched between hexagonal boron nitride

Nature Communications
The ferroelectricity in stacked van der Waals multilayers through interlayer sliding holds great promise for ultrathin high-density memory devices, yet mostly subject to weak polarization and cryogenic operating condition.
