Effects of fabrication routes and material parameters on the control of superconducting currents by gate voltage
Leon Ruf, Tosson Elalaily, Claudio Puglia +12
The control of a superconducting current via the application of a gate voltage has been recently demonstrated in a variety of superconducting devices. Although the mechanism underl…
Half-integer Shapiro steps in highly transmissive InSb nanoflag Josephson junctions
Andrea Iorio, Alessandro Crippa, Bianca Turini +8
We investigate a ballistic InSb nanoflag-based Josephson junction with Nb superconducting contacts. The high transparency of the superconductor-semiconductor interfaces enables the…
Gate control of superconducting current: Mechanisms, parameters and technological potential
Leon Ruf, Claudio Puglia, Tosson Elalaily +14
In conventional metal-oxide semiconductor (CMOS) electronics, the logic state of a device is set by a gate voltage (VG). The superconducting equivalent of such effect had remained…
Josephson Diode Effect in High Mobility InSb Nanoflags
Bianca Turini, Sedighe Salimian, Matteo Carrega +6
We report evidence of non-reciprocal dissipation-less transport in single ballistic InSb nanoflag Josephson junctions, owing to a strong spin-orbit coupling. Applying an in-plane m…
rf-SQUID measurements of anomalous Josephson effect
Claudio Guarcello, Roberta Citro, Ofelia Durante +6
We discuss the response of an rf-SQUID formed by anomalous Josephson junctions embedded in a superconducting ring with a non-negligible inductance. We demonstrate that a properly s…
