The energy band structure of graphene has two inequivalent valleys at the K and K′ points
of the Brillouin zone. The possibility to manipulate this valley degree of freedom defines the …

In the presence of a finite interlayer displacement field, bilayer graphene has an energy gap
that is dependent on stacking and largest for the stable AB and BA stacking arrangements …

Due to the unique band structure, graphene exhibits a number of exotic electronic properties
that have not been observed in other materials. Among them, it has been demonstrated that …

We investigate the valley-coupled transport of Dirac electrons in graphene with a uniform Y-
shaped Kekulé lattice distortion, in which the original K and K′ valleys of the pristine …

Elastic deformations of graphene can significantly change the flow paths and valley
polarization of the electric currents. We investigate these phenomena in graphene …

Kelvin probe force microscopy (KPFM) has been employed to probe charge carriers in a
graphene/hexagonal boron nitride (hBN) heterostructure [Nano Lett. 21, 5013 (2021) …

We propose a realizable device design for an all-electrical robust valley filter that utilizes
spin protected topological interface states hosted on monolayer 2D-Xene materials with …

The discovery of the integer quantum Hall effect in the early eighties of the last century, with
highly precise quantization values for the Hall conductance in multiples of e 2/h, has been …

We study the electronic and optical properties of single-layer phosphorene quantum dots
with various shapes, sizes, and edge types (including disordered edges) subjected to an …

Valley polarized topological kink states, existing broadly in the domain wall of hexagonal
lattice systems, are identified in experiments. Unfortunately, only very limited physical …
