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 …

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 …

We study the effect of transition-metal intercalation of graphene on the formation of a two-
dimensional topological insulator with experimentally measurable edge states. Our first …

Protected and spin-polarized transport channels are the hallmark of topological insulators,
coming along with an intrinsic strong spin–orbit coupling. Here we identified such …

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) represent a new quantum state of matter characterized by robust
gapless states inside the insulating bulk gap. The metallic edge states of a two-dimensional …

Graphene is one of the most promising materials for nanoelectronics owing to its unique
Dirac cone-like dispersion of the electronic state and high mobility of the charge carriers …

In this paper, a topological insulation GNR (graphene nanoribbon) with metallicity model is
constructed by introducing a pair of Zero-modes with equal jumping parameters into the …

Commonly, materials are classified as either electrical conductors or insulators. The
theoretical discovery of topological insulators has fundamentally challenged this dichotomy …
