The Coexistence and Decoupling of Bulk and Edge States in Disordered Two-dimensional Topological Insulators
Yan-Yang Zhang, Man Shen, Xing-Tao An +4
We investigate the scattering and localization properties of edge and bulk states in a disordered two-dimensional topological insulator when they coexist at the same fermi energy.…
Photon assisted tunneling through three quantum dots with spin-orbit-coupling
Han-Zhao Tang, Xing-Tao An, Ai-Kun Wang +1
The effect of an ac electric field on quantum transport properties in a system of three quantum dots, two of which are connected in parallel while the third is coupled to one of th…
Valley polarization in graphene-silicene-graphene heterojunction
Man Shen, Yan-Yang Zhang, Xing-Tao An +2
Considering the difference of energy bands in graphene and silicene, we put forward a new model of the graphene-silicene-graphene (GSG) heterojunction. In the GSG, we study the val…
Ferromagnetic barrier induced negative differential conductance on the surface of a topological insulator
Xing-Tao An
We theoretically investigate the effect of the negative differential conductance of a ferromagnetic barrier on the surface of a topological insulator. Due to the changes of the sha…
