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 demonstrate 3D mechanical manipulations, such as sliding, rotating, folding, flipping,
and exfoliating, of 2D materials using a microdome polymer (MDP) via in situ real-time …

Graphene has been the subject of much research, with structural engineering frequently
used to harness its various properties. In particular, the concepts of graphene origami and …

Recently, the magnetic domain walls have been experimentally observed in
antiferromagnetic topological insulators MnBi 2 Te 4. Here we study the intrinsic topological …

Pseudohelical edge state (PHES) was proposed based on a staggered spin–orbit coupling
(SOC) uniformly applied on graphene. In this work, we investigate the formation of the PHES …

We study the electronic transport properties at the intersection of three topological zero lines
as the elementary current partition node that arises in minimally twisted bilayer graphene …

We study the electronic and transport properties of a network of domain walls between
insulating domains with opposite valley Chern numbers. We find that the network is …

In AB-stacked bilayer graphene, the introduction of an out-of-plane electric field can break
the inversion symmetry to open up a nontrivial bulk gap hosting the quantum valley Hall …

Recently, a new type of second-order topological insulator has been theoretically proposed
by introducing an in-plane Zeeman field into the Kane-Mele model in the two-dimensional …

The inversion symmetry breaking in a Bernal-stacked graphene bilayer, eg, by applying a
perpendicular electric field, can open a band gap harboring the quantum valley Hall effect …
