Abstract: The stationary Josephson effect in a system of ballistic graphene is studied in the framework of quasiclassical Green's function theory. Reflecting the ultimate two-dimensionality of graphene, a Josephson junction involving a graphene sheet embodies what we call a planar Josephson junction, in which superconducting electrodes partially cover the two-dimensional graphene layer, achieving a planar contact with it. We performed tunneling spectroscopy measurements of graphene coupled to niobium/niobium-nitride superconducting electrodes. Due to the proximity effect, the graphene density of states depends on the phase difference between the superconductors and exhibits a hard induced gap at zero phase, consistent with a continuum of Andreev bound states.

  • It consists of insulating boron nitride sandwiched between two graphene sheets. Thanks to this sandwich structure and graphene's unusual properties, the incoming charge is not proportional to the voltage that is generated. Graphene exhibits unique electrical properties on account of its reduced dimensionality and “relativistic” band structure. When contacted with two superconducting electrodes, graphene can support Cooper pair transport, resulting in the well-known Josephson effect. Apr 23, 2018 · This phenomenon (Fig. 1) is similar to the flow of a supercurrent across a barrier between two superconducting regions (Josephson effect). In their system of double-bilayer graphene, Tutuc and colleagues observed one of these experimental signatures—Josephson-like tunneling .
