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…
Flux-periodic supercurrent oscillations in an Aharonov-Bohm-type nanowire Josephson junction
Patrick Zellekens, Russell S. Deacon, Farah Basaric +10
Phase winding effects in hollow semiconductor nanowires with superconducting shells have been proposed as a route to engineer topological superconducting states. We investigate GaA…
Single in situ Interface Characterization Composed of Niobium and a Selectively Grown (BiSb)Te Topological Insulator Nanoribbon
Kevin Janßen, Philipp Rüßmann, Sergej Liberda +14
With increasing attention in Majorana physics for possible quantum bit applications, a large interest has been developed to understand the properties of the interface between a …
In-plane magnetic field driven conductance modulations in topological insulator kinks
Gerrit Behner, Kristof Moors, Yong Zhang +8
We present low-temperature magnetoconductance measurements on BiSbTeSe kinks with ribbon-shaped legs. The conductance displays a clear dependence on…
Quantum transport in topological surface states of BiTe nanoribbons
Daniel Rosenbach, Nico Oellers, Abdur Rehman Jalil +8
Quasi-1D nanowires of topological insulators are emerging candidate structures in superconductor hybrid architectures for the realization of Majorana fermion based quantum computat…
