Spin-orbit coupling and electron scattering in high-quality InSbAs quantum wells
S. Metti, C. Thomas, D. Xiao +1
InSbAs is a promising material system for exploration of topological superconductivity in hybrid superconductor/semiconductor devices due to large effective g-factor…
Local and Nonlocal Transport Spectroscopy in Planar Josephson Junctions
A. Banerjee, O. Lesser, M. A. Rahman +7
We report simultaneously acquired local and nonlocal transport spectroscopy in a phase-biased planar Josephson junction based on an epitaxial InAs/Al hybrid two-dimensional heteros…
Signatures of a topological phase transition in a planar Josephson junction
A. Banerjee, O. Lesser, M. A. Rahman +12
A growing body of work suggests that planar Josephson junctions fabricated using superconducting hybrid materials provide a highly controllable route toward one-dimensional topolog…
Spin-Relaxation Mechanisms in InAs Quantum Well Heterostructures
J. D. S. Witt, S. J. Pauka, G. C. Gardner +6
The spin-orbit interaction and spin-relaxation mechanisms of a shallow InAs quantum well heterostructure are investigated by magnetoconductance measurements as a function of an app…
Spin-orbit Energies in Etch-Confined Superconductor-Semiconductor Nanowires
J. D. S. Witt, G. C. Gardner, C. Thomas +4
We report magneto-transport measurements of quasi-1-dimensional (1D) Al-InAs nanowires produced via etching of a hybrid superconductor-semiconductor two-dimensional electron gas (2…
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…
Coherent transport through a Majorana island in an Aharonov-Bohm interferometer
A. M. Whiticar, A. Fornieri, E. C. T. O'Farrell +9
Majorana zero modes are leading candidates for topological quantum computation due to non-local qubit encoding and non-abelian exchange statistics. Spatially separated Majorana mod…
High mobility InAs 2DEGs on GaSb substrates: a platform for mesoscopic quantum transport
C. Thomas, A. T. Hatke, A. Tuaz +7
High mobility, strong spin-orbit coupling, and large Landé g-factor make the two-dimensional electron gas (2DEG) in InAs quantum wells grown on nearly-lattice-matched GaSb substrat…
