Transport theory for electrical detection of the spin texture and spin-momentum locking of topological surface states
Shi-Han Zheng, Hou-Jian Duan, Mou Yang +1
The surface states of three-dimensional topological insulators exhibit a helical spin texture with spin locked to momentum. To date, however, the direct all-electrical detection of…
Signature of topological phase transition in the RKKY interaction of silicene
Hou-Jian Duan, Shi-Han Zheng, Zhen-Long Sun +2
Silicene offers an ideal platform for exploring the phase transition due to strong spin-orbit interaction and its unique structure with strong tunability. With applied electric fie…
Electronic structure and optic absorption of phosphorene under strain
Houjian Duan, Mou Yang, Ruiqiang Wang
We studied the electronic structure and optic absorption of phosphorene (monolayer of black phosphorus) under strain. Strain was found to be a powerful tool for the band structure…
Spin helical states and spin transport of the line defect in silicene lattice
Mou Yang, Dong-Hai Chen, Rui-Qiang Wang +1
We investigated the electronic structure of a silicene-like lattice with a line defect under the consideration of spin-orbit coupling. In the bulk energy gap, there are defect rela…
Valley detection using a graphene gradual pn junction with spin-orbit coupling: an analytical conductance calculation
Mou Yang, Rui-Qiang Wang, Yan-Kui Bai
Graphene pn junction is the brick to build up variety of graphene nano-structures. The analytical formula of the conductance of graphene gradual pn junctions in the whole bipolar r…
Topologically trivial and nontrivial edge bands in graphene induced by irradiation
Mou Yang, Zhi-Jun Cai, Rui-Qiang Wang +1
We proposed a minimal model to describe the Floquet band structure of two-dimensional materials with light-induced resonant inter-band transition. We applied it to graphene to stud…
