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…
