Topological insulator constrictions -- Dirac particles in a magneto-chiral box
Michael Barth, Maximilian Fürst, Raphael Kozlovsky +2
We study magneto-transport through topological insulator nanowires shaped in the form of a constriction, as can be obtained by etching techniques. The magnetic field is coaxial, po…
Theory of magnetotransport in shaped topological insulator nanowires
Ansgar Graf, Raphael Kozlovsky, Klaus Richter +1
We show that shaped topological insulator (TI) nanowires, i.e. such that their cross-section radius varies along the wire length, can be tuned into a number of different transport…
Magnetoconductance, Quantum Hall Effect, and Coulomb Blockade in Topological Insulator Nanocones
Raphael Kozlovsky, Ansgar Graf, Denis Kochan +2
Magnetotransport through cylindrical topological insulator (TI) nanowires is governed by the interplay between quantum confinement and geometric (Aharonov-Bohm and Berry) phases. H…
Probing Spin Helical Surface States in Topological HgTe Nanowires
Johannes Ziegler, Raphael Kozlovsky, Cosimo Gorini +10
Nanowires with helical surface states represent key prerequisites for observing and exploiting phase-coherent topological conductance phenomena, such as spin-momentum locked quantu…
