Abstract Two-dimensional (2D) magnetism is now the attention of central demands in fundamental condensed matter physics concerning about the understanding and control of …
The massless Dirac fermions residing on the surface of three-dimensional topological insulators are protected from backscattering and cannot be localized by disorder, but such …
We report a transport study of exfoliated few monolayer crystals of topological insulator Bi $ _2 $ Se $ _3 $ in an electric field effect (EFE) geometry. By doping the bulk crystals with Ca …
We report transport studies on magnetically doped Bi 2 Se 3 topological insulator ultrathin films grown by molecular beam epitaxy. The magnetotransport behavior exhibits a …
We study coherent electronic transport in charge-density-tunable microdevices patterned from thin films of the topological insulator (TI) Bi 2 Se 3. The devices exhibit pronounced …

We show that a number of transport properties in topological insulator (TI) Bi 2 Se 3 exhibit striking thickness dependences over a range of up to five orders of thickness (3 nm–170 …
A magnetoconductivity formula is presented for the surface states of a magnetically doped topological insulator. It reveals a competing effect of weak localization and weak …

We consider in our work single crystal thin films of Bi 2 Se 3, grown by molecular beam epitaxy, both with and without Pb doping. Angle-resolved photoemission data demonstrate …

We demonstrate that the weak antilocalization effect can serve as a convenient method for detecting decoupled surface transport in topological insulator thin films. In the regime where …
