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…
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…
Josephson Field Effect Transistors with InAs on Insulator and High Permittivity Gate Dielectrics
Alessandro Paghi, Laura Borgongino, Sebastiano Battisti +6
InAs on Insulator (InAsOI) has been recently demonstrated as a promising platform to develop hybrid semiconducting-superconducting Josephson Junctions (JJs) and Josephson Field Eff…
Cryogenic Behavior of High-Permittivity Gate Dielectrics: The Impact of the Atomic Layer Deposition Temperature and the Lithographic Patterning Method
Alessandro Paghi, Sebastiano Battisti, Simone Tortorella +2
Dielectrics featuring a high relative permittivity, i.e., high-k dielectrics, have become the standard insulators in gate architectures, enhancing the electrical performance of bot…
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…
