Active electron cooling of graphene
Federico Paolucci, Federica Bianco, Francesco Giazotto +1
In the emergent field of quantum technology, the ability to manage heat at the nanoscale and in cryogenic conditions is crucial for enhancing device performance in terms of noise,…
Electrostatic field-driven supercurrent suppression in ionic-gated metallic Josephson nanotransistors
Federico Paolucci, Francesco CrisÃ, Giorgio De Simoni +5
Recent experiments have shown the possibility of tuning the transport properties of metallic nanosized superconductors through a gate voltage. These results renewed the longstandin…
Bipolar Thermoelectric Josephson Engine
Gaia Germanese, Federico Paolucci, Giampiero Marchegiani +2
Thermoelectric effects in metals are typically small due to the nearly-perfect particle-hole (PH) symmetry around their Fermi surface [1, 2]. Despite being initially considered par…
Tailoring coherent charge transport in graphene by deterministic defect generation
Nicola Melchioni, Federico Paolucci, Paolo Marconcini +4
Harnessing the wave-nature of charge carriers in solid state devices, electron optics investigates and exploits coherent phenomena, in analogy with optics and photonics. Typically,…
Side-gate modulation of supercurrent in InSb nanoflag-based Josephson junctions
Bianca Turini, Sedighe Salimian, Matteo Carrega +4
InSb nanoflags, due to their intrinsic spin-orbit interactions, are an interesting platform in the study of planar Josephson junctions. Ballistic transport, combined with high tran…
