    • Pb-Graphene-Pb josephson junctions: Characterization in magnetic field 

      Borzenets, IV; Coskun, UC; Mebrahtu, H; Finkelstein, G (IEEE Transactions on Applied Superconductivity, 2012-06-14)
      We fabricate superconductor-graphene-superconductor Josephson junctions with superconducting regions made of lead (Pb). The critical current through graphene may be modulated by the external magnetic field; the resulting ...
    • Phase diffusion in graphene-based Josephson junctions. 

      Borzenets, IV; Coskun, UC; Jones, SJ; Finkelstein, G (Physical review letters, 2011-09-21)
      We report on graphene-based Josephson junctions with contacts made from lead. The high transition temperature of this superconductor allows us to observe the supercurrent branch at temperatures up to ∼2 K, at which point ...
    • Phonon bottleneck in graphene-based Josephson junctions at millikelvin temperatures. 

      Borzenets, IV; Coskun, UC; Mebrahtu, HT; Bomze, Yu V; Smirnov, AI; Finkelstein, G (Physical review letters, 2013-07-09)
      We examine the nature of the transitions between the normal and superconducting branches in superconductor-graphene-superconductor Josephson junctions. We attribute the hysteresis between the switching (superconducting to ...
