Josephson Junctions Via Anodization of Epitaxial Al on an InAs Heterostructure
A. Jouan, J. D. S. Witt, G. C. Gardner +5
We combine electron beam lithography and masked anodization of epitaxial aluminium to define tunnel junctions via selective oxidation, alleviating the need for wet-etch processing…
Zeeman-driven parity transitions in an Andreev quantum dot
A. M. Whiticar, A. Fornieri, A. Banerjee +6
The Andreev spectrum of a quantum dot embedded in a hybrid semiconductor-superconductor interferometer can be modulated by electrostatic gating, magnetic flux through the interfero…
Anodic Oxidation of Epitaxial Superconductor-Semiconductor Hybrids
Asbjørn C. C. Drachmann, Rosa E. Diaz, Candice Thomas +10
We demonstrate a new fabrication process for hybrid semiconductor-superconductor heterostructures based on anodic oxidation (AO), allowing controlled thinning of epitaxial Al films…
Josephson inductance as a probe for highly ballistic semiconductor-superconductor weak links
Christian Baumgartner, Lorenz Fuchs, Linus Frész +6
We present simultaneous measurements of Josephson inductance and DC transport characteristics of ballistic Josephson junctions based upon an epitaxial Al-InAs heterostructure. The…
Relating Andreev Bound States and Supercurrents in Hybrid Josephson Junctions
F. Nichele, E. Portolés, A. Fornieri +8
We investigate superconducting quantum interference devices consisting of two highly transmissive Josephson junctions coupled by a superconducting loop, all defined in an epitaxial…
Repairing the Surface of InAs-based Topological Heterostructures
S. J. Pauka, J. D. S. Witt, C. N. Allen +9
Candidate systems for topologically-protected qubits include two-dimensional electron gases (2DEGs) based on heterostructures exhibiting a strong spin-orbit interaction (SOI) and s…
