Abstract We investigate the quantum transport properties of surface electrons on a topological insulator Bi2Te3 nanowire in a magnetotransport study. Although the nanowires are synthesized by using a relatively coarse method of electrochemical deposition, clear Aharonov–Bohm oscillations of phases 0 and π are observed, owing to the highly coherent surface electron channel. The oscillation amplitude exhibits exponential temperature dependence, suggesting that the phase coherence length Lφ is… Expand
Quantum Electronic Transport of Topological Surface States in β-Ag2Se Nanowire.
First-principles band calculations revealed that the band inversion in β-Ag2Se is caused by strong spin-orbit coupling and Ag-Se bonding hybridization, providing evidence of nontrivial surface state about β- Ag2Se TIs that have anisotropic Dirac cones. Expand

Aharonov-Bohm oscillations in disordered topological insulator nanowires.
It is shown how h/e and h/2e flux oscillations of the conductance depend on doping and disorder strength, and a possible explanation for the experiments is provided, and further experiments that could verify the theory are discussed. Expand
Quasiballistic transport of Dirac fermions in a Bi2Se3 nanowire.
From their exponential temperature dependence, it is inferred that an unusual 1/T power law for the phase coherence length L(φ)(T) is typical for quasiballistic fermions weakly coupled to their environment. Expand

Experimental evidence for the modulation of surface states by using a gate voltage to control quantum oscillations in Bi(2)Te(3) nanoribbons and the first observation of h/2e periodic oscillations are reported, suggesting the presence of time-reversed paths with the same relative zero phase at the interference point.

Anomalous Aharonov-Bohm conductance oscillations from topological insulator surface states.
The conductance maxima are achieved at odd multiples of 1/2Φ(0), implying that a π AB phase for electrons strengthens the metallic nature of surface states, and a key ingredient, the surface curvature induced Berry phase, is emphasized here. Expand
Bulk band gap and surface state conduction observed in voltage-tuned crystals of the topological insulator Bi2Se3.
A transport study of exfoliated few monolayer crystals of topological insulator Bi2Se3 in an electric field effect geometry finds that the temperature T and magnetic field dependent transport properties in the vicinity of this V(g) can be explained by a bulk channel with activation gap of approximately 50 meV and a relatively high-mobility metallic channel that dominates at low T.
