Current-induced magnetization switching in a magnetic topological insulator heterostructure
Erik Zimmermann, Justus Teller, Michael Schleenvoigt +5
We present the current-induced switching of the internal magnetization direction in a magnetic topological insulator/topological insulator heterostructure in the quantum anomalous…
Fourier transformation based analysis routine for intermixed longitudinal and transversal hysteretic data for the example of a magnetic topological insulator
Erik Zimmermann, Michael Schleenvoigt, Alina Rupp +7
We present a symmetrization routine that optimizes and eases the analysis of data featuring the anomalous Hall effect. This technique can be transferred to any hysteresis with (poi…
Robust Majorana bound states in magnetic topological insulator nanoribbons with fragile chiral edge channels
Declan Burke, Dennis Heffels, Kristof Moors +3
Magnetic topological insulators in the quantum anomalous Hall regime host ballistic chiral edge channels. When proximitized by an -wave superconductor, these edge states offer t…
Robust and fragile Majorana bound states in proximitized topological insulator nanoribbons
Dennis Heffels, Declan Burke, Malcolm R. Connolly +3
Topological insulator (TI) nanoribbons with proximity-induced superconductivity are a promising platform for Majorana bound states (MBSs). In this work, we consider a detailed mode…
Probing edge state conductance in ultra-thin topological insulator films
Arthur Leis, Michael Schleenvoigt, Kristof Moors +8
Quantum spin Hall (QSH) insulators have unique electronic properties, comprising a band gap in their two-dimensional interior and one-dimensional spin-polarized edge states in whic…
Lifting the spin-momentum locking in ultra-thin topological insulator films
Arthur Leis, Michael Schleenvoigt, Vasily Cherepanov +6
Three-dimensional (3D) topological insulators (TIs) are known to carry 2D Dirac-like topological surface states in which spin-momentum locking prohibits backscattering. When thinne…
Quantum Spin-Valley Hall Kink States: From Concept to Materials Design
Tong Zhou, Shuguang Cheng, Michael Schleenvoigt +4
We propose a general and tunable platform to realize high-density arrays of quantum spin-valley Hall kink (QSVHK) states with spin-valley-momentum locking based on a two-dimensiona…
In-plane magnetic field-driven symmetry breaking in topological insulator-based three-terminal junctions
Jonas Kölzer, Kristof Moors, Abur R. Jalil +9
Topological surface states of three-dimensional topological insulator nanoribbons and their distinct magnetoconductance properties are promising for topoelectronic applications and…
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…
Magnetotransport signatures of three-dimensional topological insulator nanostructures
Kristof Moors, Peter Schüffelgen, Daniel Rosenbach +3
We study the magnetotransport properties of patterned 3D topological insulator nanostructures with several leads, such as kinks or Y-junctions, near the Dirac point with analytical…
Electrical resistance of individual defects at a topological insulator surface
Felix Lüpke, Markus Eschbach, Tristan Heider +10
Three-dimensional topological insulators host surface states with linear dispersion, which manifest as a Dirac cone. Nanoscale transport measurements provide direct access to the t…
Reinventing Solid State Electronics: Harnessing Quantum Confinement in Bismuth Thin Films
Farzan Gity, Lida Ansari, Martin Lanius +4
Solid state electronics relies on the intentional introduction of impurity atoms or dopants into a semiconductor crystal and/or the formation of junctions between different materia…
Josephson supercurrent through the topological surface states of strained bulk HgTe
Jeroen B. Oostinga, Luis Maier, Peter Schueffelgen +6
Strained bulk HgTe is a three-dimensional topological insulator, whose surface electrons have a high mobility (30,000 cm^2/Vs), while its bulk is effectively free of mobile charge…
