Superconductivity of alpha-gallium probed on the atomic scale by normal and Josephson tunneling
C. Fohn, D. Wander, D. Nikolic +6
We investigate superconducting gallium in its phase using scanning tunneling microscopy and spectroscopy at temperatures down to about 100 mK. High-resolution tunneling spectro…
Heat transport at the nanoscale and ultralow temperatures -- implications for quantum technologies
Danial Majidi, Justin P. Bergfield, Ville Maisi +3
In this perspective, we discuss thermal imbalance and the associated electron-mediated thermal transport in quantum electronic devices at very low temperatures. We first present th…
Interplay of Andreev reflection and Coulomb blockade in hybrid superconducting single electron transistors
Laura Sobral Rey, David Christian Ohnmacht, Clemens B. Winkelmann +3
We study the interplay between Coulomb blockade and superconductivity in a tunable superconductor-superconductor-normal metal single-electron transistor. The device is realized by…
High-performance electronic cooling with superconducting tunnel junctions
H Courtois, Hung Q. Nguyen, Clemens Winkelmann +1
When biased at a voltage just below a superconductor's energy gap, a tunnel junction between this superconductor and a normal metal cools the latter. While the study of such device…
Reversibility of Superconducting Nb Weak Links Driven by the Proximity Effect in a Quantum Interference Device
Nikhil Kumar, T. Fournier, H. Courtois +2
We demonstrate the role of proximity effect in the thermal hysteresis of superconducting constrictions. From the analysis of successive thermal instabilities in the transport chara…
