Atomically thin materials such as graphene and monolayer transition metal dichalcogenides
(TMDs) exhibit remarkable physical properties resulting from their reduced dimensionality …

Recently, the emerging conceptual valley-related devices have attracted much attention due
to the progress on generating, controlling, and detecting the valley degree of freedom in the …

The spontaneous Hall effect driven by the quantum Berry phase (which serves as an internal
magnetic flux in momentum space) manifests the topological nature of quasiparticles and …

Abstract 2D materials (2DMs), due to spin‐valley locking degree of freedom, exhibit strongly
bound exciton and chiral optical selection rules and become promising material candidates …

The Berry curvature in the band structure of transition metal dichalcogenides (TMDs)
introduces a valley-dependent effective magnetic field, which induces the valley Hall effect …

The interlayer interaction of vertically stacked heterojunctions is very sensitive to the
interlayer spacing, which will affect the coupling between the monolayers and allow band …

Noncentrosymmetric transition-metal dichalcogenides, particularly their 3 R polymorphs,
provide a robust setting for valleytronics. Here, we report on the selective growth of …

Twisted light carries a well-defined orbital angular momentum (OAM) of l ℏ per photon. The
quantum number l of its OAM can be arbitrarily set, making it an excellent light source to …

Exciton valley Hall effect is the spatial separation of the valley-tagged excitons by a drag
force. Usually, the effect is associated with the anomalous velocity acquired by the particles …

In twisted van der Waals (vdW) bilayers, intrinsic strain associated with the moiré
superlattice and unintentionally introduced uniaxial strain may be present simultaneously …
