Continuous and reversible tuning of the disorder-driven superconductor-insulator transition in bilayer graphene
Gil-Ho Lee, Dongchan Jeong, Kee-Su Park +3
The influence of static disorder on a quantum phase transition (QPT) is a fundamental issue in condensed matter physics. As a prototypical example of a disorder-tuned QPT, the supe…
Fano resonance in Raman scattering of graphene
Duhee Yoon, Dongchan Jeong, Hu-Jong Lee +4
Fano resonances and their strong doping dependence are observed in Raman scattering of single-layer graphene (SLG). As the Fermi level is varied by a back-gate bias, the Raman G ba…
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…
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…
Inelastic scattering in a monolayer graphene sheet; a weak-localization study
Dong-Keun Ki, Dongchan Jeong, Jae-Hyun Choi +2
Charge carriers in a graphene sheet, a single layer of graphite, exhibit much distinctive characteristics to those in other two-dimensional electronic systems because of their chir…
