Graphene is known for many of its exotic electronic properties linked to its
Dirac-type dispersion at low doping. Until quite recently, superconductivity
was missing from the list of those properties. I will show how this is a
natural consequence of the vanishing density of states at the Dirac points,
and how the situation can be cured in different types of graphene-based
systems exhibiting asymptotic flat bands. In my talk I will in explore the
different scenarios of band flattening and the associated inhomogeneous
superconductivity arising in twisted bilayer graphene, periodically strained
graphene and ABC stacked graphene. All of them have recently demonstrated to
exhibit correlated electronic states, and among them superconductivity.
