Topological insulator based axial superconducting quantum interferometer structures
Erik Zimmermann, Abdur Rehman Jalil, Michael Schleenvoigt +10
Nanoscale superconducting quantum interference devices (SQUIDs) are fabricated in-situ from a single BiSbTe nanoribbon that is defined using selective-area…
Thermal expansion and temperature dependence of Raman modes in epitaxial layers of Ge and GeSn
Agnieszka Anna Corley-Wiciak, Diana Ryzhak, Marvin Hartwig Zoellner +7
Temperature dependence of vibrational modes in semiconductors depends on lattice thermal expansion and anharmonic phonon-phonon scattering. Evaluating the two contributions from ex…
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…
Ballistic surface channels in fully in situ defined BiTe Josephson junctions with aluminum contacts
Daniel Rosenbach, Abdur R. Jalil, Tobias W. Schmitt +5
In this letter we report on the electrical transport properties of BiTe in a Josephson junction geometry using superconducting Al electrodes with a Ti interdiffusion barrie…
