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 …

Structural superlubricity, a state of ultralow friction and wear between crystalline surfaces, is
a fundamental phenomenon in modern tribology that defines a new approach to lubrication …

Electron–electron interactions play an important role in graphene and related systems and
can induce exotic quantum states, especially in a stacked bilayer with a small twist angle …

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

Structural superlubricity is a fascinating tribological phenomenon, in which the lateral
interactions between two incommensurate contacting surfaces are effectively cancelled …

Abstract Two-dimensional (2D) materials are crystalline materials made of a single or a few
layers of atoms. They have been an active research subject in recent years because of their …

Electronic and optical excitations in two-dimensional systems are distinctly sensitive to the
presence of a moiré superlattice. We used cryogenic transmission electron microscopy and …

Moiré superlattices in transition metal dichalcogenide (TMD) heterostructures can host novel
correlated quantum phenomena due to the interplay of narrow moiré flat bands and strong …

We describe the realization of van der Waals (vdW) heterostructures with accurate rotational
alignment of individual layer crystal axes. We illustrate the approach by demonstrating a …

Out-of-plane deformation patterns, such as buckling, wrinkling, scrolling, and folding, formed
by multilayer van der Waals materials have recently seen a surge of interest. One crucial …
