Charge-neutral nonlocal response in superconductor-InAs nanowire hybrid devices
A. O. Denisov, A. V. Bubis, S. U. Piatrusha +8
Nonlocal quasiparticle transport in normal-superconductor-normal (NSN) hybrid structures probes sub-gap states in the proximity region and is especially attractive in the context o…
Ultrathin catalyst-free InAs nanowires on silicon with distinct 1D sub-band transport properties
Fabio del Giudice, Jonathan Becker, Claudio de Rose +6
Ultrathin InAs nanowires (NW) with one-dimensional (1D) sub-band structure are promising materials for advanced quantum-electronic devices, where dimensions in the sub-30 nm diamet…
Heat-mode excitation in a proximity superconductor
A. O. Denisov, A. V. Bubis, S. U. Piatrusha +8
Mesoscopic superconductivity deals with various quasiparticle excitation modes, only one of them -- the charge-mode -- being directly accessible for conductance measurements due to…
Proximity effect and interface transparency in Al/InAs-nanowire/Al diffusive junctions
A. V. Bubis, A. O. Denisov, S. U. Piatrusha +6
We investigate the proximity effect in InAs nanowire (NW) junctions with superconducting contacts made of Al. The carrier density in InAs is tuned by means of the back gate voltage…
Photocurrents in a Single InAs Nanowire/ Silicon Heterojunction
Andreas Brenneis, Jan Overbeck, Julian Treu +7
We investigate the optoelectronic properties of single indium arsenide nanowires, which are grown vertically on p-doped silicon substrates. We apply a scanning photocurrent microsc…
