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…
Experimental and Theoretical Electronic Structure and Symmetry Effects in Ultrathin NbSe2 Films
Cai-Zhi Xu, Xiaoxiong Wang, Peng Chen +6
Layered quasi-two-dimensional transition metal dichalcogenides (TMDCs), which can be readily made in ultrathin films, offer excellent opportunities for studying how dimensionality…
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…
Energetics of oxygen-octahedra rotations in perovskite oxides from first principles
Peng Chen, Mathieu N. Grisolia, Hong Jian Zhao +5
We use first-principles methods to study oxygen-octahedra rotations in ABO3 perovskite oxides. We focus on the short-period, perfectly antiphase or in-phase, tilt patterns that cha…
