Topological insulators are bulk insulators that possess robust chiral conducting states along
their interfaces with normal insulators. A tremendous research effort has recently been …

Topological properties of graphene with nanoholes are theoretically investigated in detail. It
is revealed that two types of hole arrangements, honeycomb array and triangular array, give …

It is currently a promising approach to experimentally realize the topological insulator phase
transition of graphene by introducing the extrinsic spin–orbit coupling (SOC). Then …

The interplay between topology and magnetism often triggers the exotic quantum phases.
Here, we report an accessible scheme to engineer the robust $\mathbb {Z} _ {2} $ topology …

Graphene is a promising material for designing next-generation electronic and valleytronic
devices, which often demand the opening of a bandgap in the otherwise gapless pristine …

Topological insulators are an emerging class of materials that host highly robust in-gap
surface or interface states while maintaining an insulating bulk,. Most advances in this field …

To date, almost all of the discussions on topological insulators (TIs) have focused on two-
and three-dimensional systems. One-dimensional (1D) TIs manifested in real materials, in …

van der Waals (vdW) heterostructures of two-dimensional materials exhibit properties and
functionalities that can be tuned by stacking order and interlayer coupling. Although direct …

Interacting quasi-one-dimensional zigzag graphene nanoribbons display gapped edge
excitations. Although the self-consistent Hartree–Fock fields break chiral symmetry, our work …

Topological insulators (TIs) are bulk insulators that possess robust helical conducting states
along their interfaces with conventional insulators. A tremendous research effort has recently …
