Quantum Hall Andreev Conversion in Graphene Nanostructures
Alexey Bondarev, William H. Klein, Harold U. Baranger
We study Andreev conversion in clean nanostructures containing an interface between graphene in the quantum Hall (QH) state and a superconductor, focusing on the lowest Landau leve…

Transparent Graphene-Superconductor Interfaces: Quantum Hall and Zero Field Regimes
Alexey Bondarev, Gu Zhang, Harold U. Baranger
We study clean, edge-contacted graphene/superconductor interfaces in both the quantum Hall (QH) and zero field regimes. We find that Andreev reflection is substantially stronger th…
