Edge dependence of the Josephson current in the quantum Hall regime
Seong Jang, Geon-Hyoung Park, Kenji Watanabe +2
The observation of Josephson current in the quantum Hall regime has attracted considerable attention, revealing the coexistence of two seemingly incompatible phases: the quantum Ha…
Engineering superconducting contacts transparent to a bipolar graphene
Seong Jang, Geon-Hyoung Park, Sein Park +4
Graphene's exceptional electronic mobility, gate-tunability, and contact transparency with superconducting materials make it ideal for exploring the superconducting proximity effec…
Controllable Andreev Bound States in Bilayer Graphene Josephson Junction from Short to Long Junction Limits
Geon-Hyoung Park, Wonjun Lee, Sein Park +4
We demonstrate that the mode number of Andreev bound states in bilayer graphene Josephson junctions can be modulated by in situ control of the superconducting coherence length. By…
Observation of negative refraction of Dirac fermions in graphene
Gil-Ho Lee, Geon-Hyoung Park, Hu-Jong Lee
Half a century ago, Veselago proposed left-handed materials with negative permittivity and permeability, in which waves propagate with phase and group velocities in opposite direct…
