Near a magic twist angle, bilayer graphene transforms from a weakly correlated Fermi liquid
to a strongly correlated two-dimensional electron system with properties that are …

When single layers of 2D materials are stacked on top of one another with a small twist in
orientation, the resulting structure often involves incommensurate moiré patterns. In these …

Moiré superlattices of twisted nonmagnetic two-dimensional (2D) materials are highly
controllable platforms for the engineering of exotic correlated and topological states. Here …

Conventional antiferroelectric materials with atomic-scale anti-aligned dipoles undergo a
transition to a ferroelectric (FE) phase under strong electric fields. The moiré superlattice …

Control of the interlayer twist angle in two-dimensional van der Waals (vdW)
heterostructures enables one to engineer a quasiperiodic moiré superlattice of tunable …

Magic-angle twisted trilayer graphene (TTG) has recently emerged as a platform to engineer
strongly correlated flat bands. We reveal the normal-state structural and electronic properties …

Moiré patterns of transition metal dichalcogenide heterobilayers have proved to be an ideal
platform on which to host unusual correlated electronic phases, emerging magnetism and …

Quantum materials have attracted much attention in recent years due to their exotic and
incredible properties. Among them, van der Waals materials stand out due to their weak …

Van der Waals heterostructures form a unique class of layered artificial solids in which
physical properties can be manipulated through controlled composition, order and relative …

Van der Waals heteroepitaxy allows deterministic control over lattice mismatch or azimuthal
orientation between atomic layers to produce long-wavelength superlattices. The resulting …
