The discovery of ferroelectricity in two-dimensional (2D) van der Waals (vdW) materials has
brought important functionalities to the 2D materials family, and may trigger a revolution in …

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

Neuromorphic computing based on emerging devices could overcome the von Neumann
bottleneck—the restriction created by having to transfer data between memory and …

Abstract van der Waals materials have greatly expanded our design space of
heterostructures by allowing individual layers to be stacked at non-equilibrium …

Despite their partial ionic nature, many-layered diatomic crystals avoid internal electric
polarization by forming a centrosymmetric lattice at their optimal van der Waals stacking …

Ferroelectric materials are fascinating for their non-volatile switchable electric polarizations
induced by the spontaneous inversion-symmetry breaking. However, in all of the …

Achieving electrostatic control of quantum phases is at the frontier of condensed matter
research. Recent investigations have revealed superconductivity tunable by electrostatic …

The long-wavelength moiré superlattices in twisted 2D structures have emerged as a highly
tunable platform for strongly correlated electron physics. We study the moiré bands in …

Multiferroic materials have attracted wide interest because of their exceptional static,–and
dynamical,–magnetoelectric properties. In particular, type-II multiferroics exhibit an inversion …

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 …
