I guess a graphene bilayer has some properties that, under the right circumstances, could make it a superconductor.

That particular report falls into the most-likely-bogus category.
- Several other groups have done the identical experiment on almost identical samples and not seen this.
- There is no particular connection between what they report and superconductivity. The idea relies upon a weak argument by analogy, i.e. there is an important high temperature superconductor with such a flat band.
- Really important results in this area that colleagues believe are not published in Science Advances.
Superconductivity in twisted graphene discussed higher up in this thread does seem to be real and interesting.
[Weird forum bug. Occasionally when I try to post, the message I write doesn't appear but instead the quotation of the OP shows up twice. I think this only happens when I used Microsoft Edge. Anyone else notice this or know why? ]
