A Voltage-Controlled Josephson Frequency Comb
Giorgio De Simoni, Francesco Giazotto
Microwave frequency combs constitute promising resources for quantum technologies, cryogenic electronics, and multiplexed sensing architectures. In this work, we propose a frequenc…
Superconducting properties of lifted-off Niobium nanowires
A. Kotsovolou, F. Soofivand, P. Singha +7
Hybrid superconductor/semiconductor devices play a crucial role in advancing quantum science and technology by merging the properties of superconductors and semiconductors. To oper…
A Zero-Bias Superconducting Voltage Amplifier Based on the Bipolar Thermoelectric Effect
Giacomo Trupiano, Giorgio De Simoni, Francesco Giazotto
We introduce a zero-bias superconducting voltage amplifier that harvests energy from a thermal gradient by exploiting negative differential resistance (NDR) in an asymmetric tunnel…
Extremely weak electron-phonon coupling in Josephson junctions built on InAs on Insulator
Giorgio De Simoni, Sebastiano Battisti, Alessandro Paghi +2
InAs-on-Insulator (InAsOI) enables an effective superconducting proximity effect and extremely weak electron-phonon (e-ph) coupling, allowing precise electronic-temperature control…
Giant thermal modulation via a semiconductor-superconductor photonic field-effect heat transistor
Sebastiano Battisti, Matteo Pioldi, Alessandro Paghi +5
We present a groundbreaking demonstration of thermal modulation in a field-effect-controllable semiconductor-superconductor hybrid structure, wherein the heating mechanism is exclu…
Highly-Linear Proximity-Based Bi-SQUID Operating above 4 K
G. Trupiano, E. Riccardi, C. Puglia +5
We demonstrate a highly linear superconducting quantum interference device (SQUID) amplifier based on a double-loop (Bi-SQUID) architecture incorporating three superconductor-norma…
