Electrically tunable multiple Dirac cones in thin films of (LaO)2(SbSe2)2 family of materials
Xiao-Yu Dong, Jian-Feng Wang, Rui-Xing Zhang +4
Two-dimensional Dirac physics has aroused great interests in condensed matter physics ever since the discovery of graphene and topological insulators due to its importance in both…
Effects of excitation frequency on high-order terahertz sideband generation in semiconductors
Xiao-Tao Xie, Bang-Fen Zhu, Ren-Bao Liu
We theoretically investigate the effects of the excitation frequency on the plateau of high-order terahertz sideband generation (HSG) in semiconductors driven by intense terahertz…
Single Dirac point and helical states in a one-dimensional system
Sheng-Nan Ji, Bang-Fen Zhu, Ren-Bao Liu
Odd numbers of Dirac points and helical states can exist at edges (surfaces) of two-dimensional (three-dimensional) topological insulators. In the bulk of a one-dimensional lattice…
Elastic scattering of surface states on three-dimensional topological insulators
Jing Wang, Bang-Fen Zhu
Topological insulators as new type of quantum matter materials are characterized by a full insulating gap in the bulk and gapless edge/surface states which are protected by time-re…
Optical effects of spin currents in semiconductors
Jing Wang, Sheng-Nan Ji, Bang-Fen Zhu +1
A spin current has novel linear and second-order nonlinear optical effects due to its symmetry properties. With the symmetry analysis and the eight-band microscopic calculation we…
Topological p-n Junction
Jing Wang, Xi Chen, Bang-Fen Zhu +1
We consider a junction between surface -type and surface -type on an ideal topological insulator in which carrier type and density in two adjacent regions are locally control…
