Proximity-induced superconductivity in single-layer and bilayer graphene

Bordaz, Julien

Abstract:
In this work, the properties of proximity-induced superconductivity in graphene and bilayer graphene are investigated. We report the realisation and study of a dual-gated bilayer graphene sheet connected with superconducting electrodes. Our measurements at 7 mK show that the induced supercurrent vanishes around the charge neutrality point and that the amplitude of the critical current as well as the normal-state resistance can be tuned by the displacement field induced by the two gates.
