Encapsulated Superconducting Graphene Nanodevices for Transport and Spectroscopic Studies

ORAL

Abstract

Through proximity effect, graphene provides an ideal platform to study mesoscopic superconductivity and other quantum phenomena when it is in contact with superconductors. The advancement in the fabrication techniques of 2-D Van der Waals heterostructures has brought the superconducting graphene nanodevice into ballistic regime and made it suitable for a variety of studies. We show superconducting graphene nanodevices encapsulated in hexagonal boron nitride (hBN) thin films. The pristine graphene can be proximitized by superconducting leads, manipulated by local gating and probed by tunneling leads in order to explore various kinds of physics.
