Fractional quantum ferroelectricity
Nature Communications, 2023 For an ordinary ferroelectric, the magnitude of the spontaneous electric polarization is at least one order of magnitude smaller than that resulting from the ionic displacement of the lattice vectors, and the direction of the spontaneous electric ...

Purely in-plane ferroelectricity in monolayer SnS at room temperature [PDF]
Nature Communications, 2020 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

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.
