Overdamped Phase Diffusion in hBN Encapsulated Graphene Josephson Junctions
J. Tang, M. T. Wei, A. Sharma +7
We investigate the zero-bias behavior of Josephson junctions made of encapsulated graphene boron nitride heterostructures in the long ballistic junction regime. For temperatures do…
Chiral Quasiparticle Tunneling Between Quantum Hall Edges in Proximity with a Superconductor
M. T. Wei, A. W. Draelos, A. Seredinski +10
We study a two-terminal graphene Josephson junction with contacts shaped to form a narrow constriction, less than 100nm in length. The contacts are made from type II superconductin…
Supercurrent Flow in Multi-Terminal Graphene Josephson Junctions
Anne W. Draelos, Ming-Tso Wei, Andrew Seredinski +7
We investigate the electronic properties of ballistic planar Josephson junctions with multiple superconducting terminals. Our devices consist of monolayer graphene encapsulated in…
Supercurrent in Graphene Josephson Junctions with Narrow Trenches in the Quantum Hall Regime
Andrew Seredinski, Anne Draelos, Ming-Tso Wei +12
Coupling superconductors to quantum Hall edge states is the subject of intense investigation as part of the ongoing search for non-abelian excitations. Our group has previously obs…
