Electrically Tunable Macroscopic Quantum Tunneling in a Graphene-based Josephson Junction
Gil-Ho Lee, Dongchan Jeong, Jae-Hyun Choi +2
Stochastic switching-current distribution in a graphene-based Josephson junction exhibits a crossover from the classical to quantum regime, revealing the macroscopic quantum tunnel…
Above-gap Conductance Anomaly Studied in Superconductor-graphene-superconductor Josephson Junctions
Jae-Hyun Choi, Hu-Jong Lee, Yong-Joo Doh
We investigated the electrical transport properties of superconductor-graphene-superconductor (SGS) Josephson junctions. In low voltage bias, we observed conventional proximity-cou…
Observation of Supercurrent in PbIn-Graphene-PbIn Josephson Junction
Dongchan Jeong, Jae-Hyun Choi, Gil-Ho Lee +3
Superconductor-graphene-superconductor (SGS) junction provides a unique platform to study relativistic electrodynamics of Dirac fermions combined with proximity-induced superconduc…
