Structurally different from conventional oxide ferroelectrics with rigid lattices, van der Waals
(vdW) ferroelectrics have stable layered structures with a combination of strong intralayer …

In recent years, an increasing number of 2D van der Waals (vdW) materials are theory‐
predicted or laboratory‐validated to possess in‐plane (IP) and/or out‐of‐plane (OOP) …

Sliding ferroelectricity is a recently observed polarity existing in two-dimensional materials.
However, due to the weak polarization and poor electrical insulation in these materials …

Most nonferroelectric two-dimensional materials can be endowed with so-called sliding
ferroelectricity via nonequivalent homobilayer stacking, which is not applicable to …

Ferroelectricity in atomically thin bilayer structures has been recently predicted and
measured,–in two-dimensional materials with hexagonal non-centrosymmetric unit-cells …

Ferroelectricity in ultrathin two-dimensional (2D) materials has attracted broad interest due
to potential applications in nonvolatile memory, nanoelectronics and optoelectronics …

Two-dimensional (2D) ferroelectrics, which are rare in nature, enable high-density
nonvolatile memory with low energy consumption. Here, we propose a theory of bilayer …

Near the 100th anniversary of the discovery of ferroelectricity, so-called sliding
ferroelectricity has been proposed and confirmed recently in a series of experiments that …

Since the discovery of Rochelle salt a century ago, ferroelectric materials have been
investigated extensively due to their robust responses to electric, mechanical, thermal …

Stacking orders in 2D van der Waals (vdW) materials dictate the relative sliding (lateral
displacement) and twisting (rotation) between atomically thin layers. By altering the stacking …
