Imaging of Gate-Controlled Suppression of Superconductivity via the Meissner Effect
P. J. Scheidegger, K. J. Knapp, U. Ognjanovic +5
It was recently discovered that supercurrents flowing through thin superconducting nanowires can be quenched by a gate voltage. This gate control of supercurrents, known as the GCS…
Implantation studies of low-energy positive muons in niobium thin films
Ryan M. L. McFadden, Andreas Suter, Leon Ruf +5
Here we study the range of keV positive muons implanted in NbO( nm)/Nb( nm)/SiO(300 nm)/Si [ = 3.6 nm, 3.3 nm; = 42.0 nm, 60.1 nm] thin films using l…
Superconducting non-volatile memory based on charge trapping and gate-controlled supercurrent
Leon Ruf, Angelo Di Bernardo, Elke Scheer
Superconducting electronics holds great promise for energy-efficient high-performance and quantum computing, yet no superconducting memory has matched the performance of convention…
High-performance gate-controlled superconducting switches: large output voltage and reproducibility
Leon Ruf, Elke Scheer, Angelo Di Bernardo
Logic circuits consist of devices that can be controlled between two distinct states. The recent demonstration that a superconducting current flowing in a constriction can be contr…
