Fabrication and characterization of InAs nanowire-based quantum dot structures utilizing buried bottom gates
Anton Faustmann, Patrick Liebisch, Benjamin Bennemann +6
Semiconductor nanowires can be utilized to create quantum dot qubits. The formation of quantum dots is typically achieved by means of bottom gates created by a lift-off process. As…
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…
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…
Microwave spectroscopy of Andreev states in InAs nanowire-based hybrid junctions using a flip-chip layout
Patrick Zellekens, Russell Deacon, Pujitha Perla +4
Josephson junctions based on semiconductor nanowires are potential building blocks for electrically tunable qubit structures, e.g. the gatemon or the Andreev qubit. However, an act…
Te-doped selective-area grown InAs nanowires for superconducting hybrid devices
Pujitha Perla, Anton Faustmann, Sebastian Koelling +11
Semiconductor nanowires have emerged as versatile components in superconducting hybrid devices for Majorana physics and quantum computing. The transport properties of nanowires can…
Flux periodic oscillations and phase-coherent transport in GeTe nanowire-based devices
Jinzhong Zhang, Pok-Lam Tse, Abdur-Rehman Jalil +9
Despite the fact that GeTe is known to be a very interesting material for applications in thermoelectrics and for phase-change memories, the knowledge on its low-temperature transp…
MBE Growth of Al/InAs and Nb/InAs Superconducting Hybrid Nanowire Structures
Nicholas A. Güsken, Torsten Rieger, Benjamin Bennemann +4
We report on \textit{in situ} growth of crystalline Al and Nb shells on InAs nanowires. The nanowires are grown on Si(111) substrates by molecular beam epitaxy (MBE) without foreig…
Realization of a vertical topological p-n junction in epitaxial heterostructures
Markus Eschbach, Ewa Mlynczak, Jens Kellner +17
3D topological insulators are a new state of quantum matter which exhibits both a bulk band structure with an insulating energy gap as well as metallic spin-polarized Dirac fermion…
