Valley-selective circular dichroism of monolayer molybdenum disulphide
Ting Cao,Gang Wang,Wen-Peng Han,Huiqi Ye,Chuanrui Zhu,Junren Shi,Qian Niu,Qian Niu,Ping-Heng Tan,Enge Wang,Baoli Liu,Ji Feng +11 more
TL;DR: It is shown, using first principles calculations, that monolayer molybdenum disulphide is an ideal material for valleytronics, for which valley polarization is achievable via valley-selective circular dichroism arising from its unique symmetry.
Journal ArticleDOI
Gate-Voltage Control of Chemical Potential and Weak Antilocalization in Bi 2 Se 3
J. C. Chen,Huajun Qin,Fan Yang,J. Liu,Tong Guan,Fanming Qu,G. H. Zhang,Junren Shi,X. C. Xie,X. C. Xie,C. L. Yang,Kehui Wu,Yu Li,Ling Lu +13 more
TL;DR: A much suppressed bulk conductivity at large negative gate voltages is suggested and a possible role of surface states in the WAL phenomena is suggested.
Journal ArticleDOI
Berry phase correction to electron density of states in solids.
Di Xiao,Junren Shi,Qian Niu +2 more
TL;DR: In this paper, a modification of the phase-space density of states of Bloch electrons is discussed, whose significance is discussed in a number of examples: field modification of Fermi-sea volume, connection to the anomalous Hall effect, and a general formula for orbital magnetization.
Journal ArticleDOI
Competition between Weak Localization and Antilocalization in Topological Surface States
TL;DR: A magnetoconductivity formula is presented, found that, while random magnetic scattering always drives the system from the symplectic to the unitary class, the gap could induce a crossover from weak antilocalization to weak localization, tunable by the Fermi energy or the gap.
Journal ArticleDOI
Proper definition of spin current in spin-orbit coupled systems.
TL;DR: A proper and measurable spin current is established in this study, which fits well into the standard framework of near-equilibrium transport theory and has the desirable property to vanish in insulators with localized orbitals.
