Topological property of graphene with triangular array of nanoholes
Yong-Cheng Jiang, Xing-Xiang Wang, Xiao Hu
The nontrivial band topology for graphene with regular arrays of nanoholes with symmetry is investigated theoretically. For the case of triang…
Periodic Behavior of Topology in Graphene with Nanohole Array
Yong-Cheng Jiang, Xing-Xiang Wang, Xiao Hu
We derive a way to diagnose band topology for graphene with triangular and/or honeycomb array of nanoholes directly from the lattice constant of superstructure $m\sqrt{3}\times m\s…
Comment on "Absence of Topological Protection of the Interface States in Photonic Crystals"
Xing-Xiang Wang, Toshikaze Kariyado, Xiao Hu
In the Letter, Xu et al. reported that edge modes disappear in the expanded structure of Wu-Hu model characterized by topological index, while appear in the trivial…
Higher-order topology in honeycomb lattice with Y-Kekulé distortions
Yong-Cheng Jiang, Toshikaze Kariyado, Xiao Hu
We investigate higher-order topological states in honeycomb lattice with Y-Kekulé distortions that preserve crystalline symmetry. The gapped states in expanded and shrunke…
Possible gapless helical edge states in hydrogenated graphene
Yong-Cheng Jiang, Toshikaze Kariyado, Xiao Hu
Electronic band structures in hydrogenated graphene are theoretically investigated by means of first-principle calculations and an effective tight-binding model. It is shown that r…
Topological electronic states in holey graphyne
Yong-Cheng Jiang, Toshikaze Kariyado, Xiao Hu
We unveil that the holey graphyne (HGY), a two-dimensional carbon allotrope where benzene rings are connected by two CC bonds fabricated recently in a bottom-up way,…
