Dirac semimetal phase in the hexagonal LiZnBi
Wendong Cao, Peizhe Tang, Yong Xu +3
Based on first-principles calculations, we find that LiZnBi, a metallic hexagonal compound, can be driven into a Dirac semimetal with a pair of Dirac points by strain. The no…
Converting normal insulators into topological insulators via tuning orbital levels
Wu-Jun Shi, Junwei Liu, Yong Xu +3
Tuning the spin-orbit coupling strength via foreign element doping and/or modifying bonding strength via strain engineering are the major routes to convert normal insulators to top…
A general group theoretical method to unfold band structures and its application
Huaqing Huang, Fawei Zheng, Ping Zhang +3
We present a general method to unfold energy bands of supercell calculations to primitive Brillouin zone using group theoretical techniques, where an isomorphic factor group is int…
Functionalized Germanene as a Prototype of Large-Gap Two-Dimensional Topological Insulators
Chen Si, Junwei Liu, Yong Xu +3
We propose new two-dimensional (2D) topological insulators (TIs) in functionalized germanenes (GeX, X=H, F, Cl, Br or I) using first-principles calculations. We find GeI is a 2D TI…
Electronic transmission in Graphene suppressed by interlayer interference
Daniel Valencia, Jun-Qiang Lu, Jian Wu +3
We investigate electronic transport property of a graphene monolayer covered by a graphene nanoribbon. We demonstrate that electronic transmission of a monolayer can be reduced whe…
Manipulating the magnetic anisotropy of cobalt doped titanium dioxide by carrier accumulation
Bin Shao, Min Feng, Hong Liu +2
Based on first-principles calculations, we predict that the magnetic anisotropy energy (MAE) of Co-doped TiO sensitively depends on carrier accumulation. This magnetoelectric p…
