Wet etch methods for InAs nanowire patterning and self-aligned electrical contacts
G. Fülöp, S. d'Hollosy, L. Hofstetter +4
Advanced synthesis of semiconductor nanowires (NWs) enables their application in diverse fields, notably in chemical and electrical sensing, photovoltaics, or quantum electronic de…
Entanglement witnessing in superconducting beamsplitters
H. Soller, L. Hofstetter, D. Reeb
We analyse a large class of superconducting beamsplitters for which the Bell parameter (CHSH violation) is a simple function of the spin detector efficiency. For these superconduct…
Kondo effect and spin-active scattering in ferromagnet-superconductor junctions
H. Soller, L. Hofstetter, S. Csonka +3
We study the interplay of superconducting and ferromagnetic correlations on charge transport in different geometries with a focus on both a quantum point contact as well as a quant…
Finite bias Cooper pair splitting
L. Hofstetter, S. Csonka, A. Baumgartner +4
In a device with a superconductor coupled to two parallel quantum dots (QDs) the electrical tunability of the QD levels can be used to exploit non-classical current correlations du…
Ferromagnetic proximity effect in F-QDot-S device
L. Hofstetter, S. Csonka, A. Geresdi +3
Ferromagnetic proximity effect is studied in InAs nanowire (NW) based quantum dots (QD) strongly coupled to a ferromagnetic (F) and a superconducting (S) lead. The influence of the…
Giant fluctuations and gate control of the g-factor in InAs Nanowire Quantum Dots
S. Csonka, L. Hofstetter, F. Freitag +5
We study the g-factor of discrete electron states in InAs nanowire based quantum dots. The g values are determined from the magnetic field splitting of the zero bias anomaly due to…
