Scanning Gate Microscopy Modulation of Supercurrent in Graphene Josephson Junctions
Ivan Villani, Samuele Fracassi, Niccolò Traverso Ziani +9
The paper uses scanning gate microscopy to locally modulate and map the supercurrent in hBN‑encapsulated graphene Josephson junctions with niobium contacts, analyzing how tip volta…
Graphene Josephson diodes from inherent asymmetric disorder
Ivan Villani, Luca Chirolli, Matteo Carrega +10
Josephson diodes are non-reciprocal superconducting devices characterized by different switching currents depending on the current flow direction. They recently attracted considera…
Quasi--periodic supercurrent at quantum Hall transitions
Ivan Villani, Matteo Carrega, Alessandro Crippa +9
The combination of superconductivity and quantum Hall (QH) effect is regarded as a key milestone in advancing topological quantum computation in solid-state systems. Recent quantum…
