Graphene-based quantum Hall interferometer with self-aligned side gates
Lingfei Zhao, Ethan G. Arnault, Trevyn F. Q. Larson +7
The vanishing band gap of graphene has long presented challenges for making high-quality quantum point contacts (QPCs) -- the partially transparent p-n interfaces introduced by con…
Full control of quantum Hall supercurrent in a side gated graphene Josephson junction
Andrew Seredinski, Anne W. Draelos, Ethan G. Arnault +6
We present a study of a graphene-based Josephson junction with dedicated side gates carved from the same sheet of graphene as the junction itself. These side gates are highly effic…
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…
