TLDR
In this paper, the appearance of superconducting states when changing magnetic field and carrier concentration has been investigated, and some proximity effect survives for fields above 1'T for Josephson junctions based on graphene.Abstract:
Josephson junctions based on graphene exhibit tunable proximity effects. The appearance of superconducting states when changing magnetic field and carrier concentration has now been investigated—some proximity effect survives for fields above 1 T.read more

Chiral tunnelling and the Klein paradox in graphene
TL;DR: In this paper, it was shown that the Klein paradox can be tested in a conceptually simple condensed-matter experiment using electrostatic barriers in single and bi-layer graphene, showing that quantum tunnelling in these materials becomes highly anisotropic, qualitatively different from the case of normal, non-relativistic electrons.
