Phase-coherent loops in selectively-grown topological insulator nanoribbons
Jonas Kölzer, Daniel Rosenbach, Christian Weyrich +9
Universal conductance fluctuations and the weak antilocalization effect are defect structure specific fingerprints in the magnetoconductance that are caused by electron interferenc…
Quantum Interference Effects in Topological Nanowires In a Longitudinal Magnetic Field
Vincent E. Sacksteder, Quansheng Wu
We study the magnetoconductance of topological insulator nanowires in a longitudinal magnetic field, including Aharonov-Bohm, Altshuler-Aronov-Spivak, perfectly conducting channel,…
Topological Effects on the Magnetoconductivity in Topological Insulators
Vincent E. Sacksteder, Kristin Bjorg Arnardottir, Stefan Kettemann +1
Three-dimensional strong topological insulators (TIs) guarantee the existence of a 2-D conducting surface state which completely covers the surface of the TI. The TI surface state…
Hole Spin Helix: Anomalous Spin Diffusion in Anisotropic Strained Hole Quantum Wells
Vincent E. Sacksteder, B. Andrei Bernevig
We obtain the spin-orbit interaction and spin-charge coupled transport equations of a two-dimensional heavy hole gas under the influence of strain and anisotropy. We show that a si…
Parallel field magnetoresistance in topological insulator thin films
C. J. Lin, X. Y. He, J. Liao +11
We report that the finite thickness of three-dimensional topological insulator (TI) thin films produces an observable magnetoresistance (MR) in phase coherent transport in parallel…
Robust topological insulator surface conduction under strong surface disorder
Quansheng Wu, Liang Du, Vincent E. Sacksteder
Topological insulators are characterized by specially protected conduction on their outer boundaries. We show that the protected edge conduction exhibited by 2-D topological insula…
