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

Purely in-plane ferroelectricity in monolayer SnS at room temperature [PDF]
Out-of-plane ferroelectricity is usually unstable in the two dimensional limit due to the presence of the depolarization field. Here, the authors successfully circumvent this issue by growing µm-sized SnS monolayers that exhibit in-plane ferroelectricity

An antisite defect mechanism for room temperature ferroelectricity in orthoferrites [PDF]
Ferroelectricity in orthoferrite perovskites has stimulated intense research, but the mechanism remains unclear. Here, the authors propose an antisite defect mechanism for introducing ferroelectricity in magnetically ordered YFeO3 and the family of rare ...

Interfacial ferroelectricity in rhombohedral-stacked bilayer transition metal dichalcogenides [PDF]
van der Waals materials have greatly expanded our design space of heterostructures by allowing individual layers to be stacked at non-equilibrium configurations, for example via control of the twist angle.

Interfacial ferroelectricity in marginally twisted 2D semiconductors [PDF]
Twisted heterostructures of two-dimensional crystals offer almost unlimited scope for the design of new metamaterials. Here we demonstrate a room temperature ferroelectric semiconductor that is assembled using mono- or few-layer MoS2. These van der Waals

Sliding ferroelectricity in van der Waals layered γ-InSe semiconductor
Exploring two-dimensional layered ferroelectric semiconductors is highly desired for ferroelectric-based devices. Here, the authors realize the room-temperature ferroelectricity in layered Y-doped γ-InSe due to the microstructure modifications.

Two-dimensional ferroelectricity in a single-element bismuth monolayer
A single-element ferroelectric state is observed in a black phosphorus-like bismuth layer, in which the ordered charge transfer and the regular atom distortion between sublattices happen simultaneously and ferroelectric switching is further visualized ...
