Engineering Hybrid Epitaxial InAsSb/Al Nanowire Materials for Stronger Topological Protection
Joachim E. Sestoft, Thomas Kanne, Aske Nørskov Gejl +11
The combination of strong spin-orbit coupling, large -factors, and the coupling to a superconductor can be used to create a topologically protected state in a semiconductor nano…
Effective g-factor in Majorana Wires
S. Vaitiekėnas, M. T. Deng, J. Nygård +2
We use the effective g-factor of subgap states, g*, in hybrid InAs nanowires with an epitaxial Al shell to investigate how the superconducting density of states is distributed betw…
Hybrid nanowire ion-to-electron transducers for integrated bioelectronic circuitry
D. J. Carrad, A. B. Mostert, A. R. Ullah +8
A key task in the emerging field of bioelectronics is the transduction between ionic/protonic and electronic signals at high fidelity. This is a considerable challenge since the tw…
Towards low-dimensional hole systems in Be-doped GaAs nanowires
A. R. Ullah, J. G. Gluschke, P. Krogstrup +3
GaAs was central to the development of quantum devices but is rarely used for nanowire-based quantum devices with InAs, InSb and SiGe instead taking the leading role. p-type GaAs n…
Majorana bound states in a coupled quantum-dot hybrid-nanowire system
M. T. Deng, S. Vaitiekenas, E. B. Hansen +6
Hybrid nanowires combining semiconductor and superconductor materials appear well suited for the creation, detection, and control of Majorana bound states (MBSs). We demonstrate th…
