Topological Properties of Gapped Graphene Nanoribbons with Spatial Symmetries
Kuan-Sen Lin, Mei-Yin Chou
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…
In-situ strain tuning of the Dirac surface states in Bi2Se3 films
David Floetotto, Yang Bai, Yang-Hao Chan +12
Elastic strain has the potential for a controlled manipulation of the band gap and spin-polarized Dirac states of topological materials, which can lead to pseudo-magnetic-field eff…
Quantum-spin-Hall insulator with a large gap: single-layer 1T' WSe
P. Chen, W. -W. Pai, Y. -H. Chan +6
Two-dimensional (2D) topological insulators (TIs) are promising platforms for low-dissipation spintronic devices based on the quantum spin Hall (QSH) effect, but experimental reali…
Electrical valley filtering in transition metal dichalcogenides
Tzu-Chi Hsieh, Mei-Yin Chou, Yu-Shu Wu
This work investigates the feasibility of electrical valley filtering for holes in transition metal dichalcogenides. We look specifically into the scheme that utilizes a potential…
