Streamline controlled rectification of supercurrent in thin-film asymmetric weak links
Filippo Antola, Sebastiano Battisti, Alessandro Braggio +2
In this study, we examined the supercurrent diode effect (SDE) in mesoscopic superconducting weak links formed by asymmetric Dayem bridges. These planar metallic constrictions, whi…
Extremely weak sub-kelvin electron-phonon coupling in InAs On Insulator
Sebastiano Battisti, Giorgio De Simoni, Alessandro Braggio +3
We are proposing, as an ideal candidate for caloritronic devices operating at subKelvin temperatures, a hybrid superconductor-semiconductor platform named InAs on insulator (InAsOI…
Quasi-ideal feedback-loop supercurrent diode
Giorgio De Simoni, Francesco Giazotto
We suggest using a device called the Bootstrap Superconducting Quantum Interference Device (BS-SQUID) to break the reciprocity in charge transport. This device uses magnetic flux b…
Gate-controlled supercurrent effect in dry-etched Dayem bridges of non-centrosymmetric niobium rhenium
Jennifer Koch, Carla Cirillo, Sebastiano Battisti +10
The application of a gate voltage to control the superconducting current flowing through a nanoscale superconducting constriction, named as gate-controlled supercurrent (GCS), has…

S. Battisti, J. Koch, A. Paghi +10
Here we demonstrate superconducting Dayem-bridge weak-links made of different stoichiometric compositions of NbRe. Our devices possess a relatively high critical temperature, norma…
Bipolar thermoelectric superconducting single-electron transistor
Sebastiano Battisti, Giorgio De Simoni, Luca Chirolli +2
Thermoelectric effects in normal metals and superconductors are usually very small due to the presence of electron-hole symmetry. Here, we show that superconducting junctions broug…
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…
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…
Ultra linear magnetic flux-to-voltage conversion in superconducting quantum interference proximity transistors
Giorgio De Simoni, Francesco Giazotto
Superconducting interferometers are quantum devices able to transduce a magnetic flux into an electrical output with excellent sensitivity, integrability and power consumption. Yet…
