Proximity-induced superconductivity in a bilayer graphene quantum point contact
Clara Galante-Agero, Christoph Adam, Artem O. Denisov +9
We report the realization of a gate-defined quantum point contact (QPC) in bilayer graphene proximitized by a single aluminum superconducting electrode. Superconducting correlation…
Vortex Dynamics in Magic-Angle Twisted Graphene
Marta Perego, Peter Koopmann, Clara Galante Agero +7
We use a gate-defined Josephson junction (JJ) device made from twisted-layer graphene for studying vortex dynamics in two dimensions. The JJ sensor signals the presence of individu…
Monolithic hybrid quantum dot devices in superconducting twisted bilayer graphene
Alexandra Mestre-Torà, Marta Perego, Clara Galante Agero +5
Gate-tunable superconductivity in magic-angle twisted bilayer graphene (MATBG) has enabled the realization of superconducting devices, such as Josephson junctions, within a single…
Experimental detection of vortices in magic-angle graphene
Marta Perego, Clara Galante Agero, Alexandra Mestre Torà +9
The tunability of superconducting magic-angle twisted-layer graphene films elevates this material system to a promising candidate for superconducting electronics. We implement a ga…
