Superconductivity induced by the intervalley Coulomb scattering in a few layers of graphene

We study the intervalley scattering induced by Coulomb repulsion as a purely electronic mechanism for origin of superconductivity in few layers graphene. The pairing is strongly favored presence van Hove singularities density states. consider three different heterostructures: twisted bilayer graphene, rhombohedral trilayer and Bernal obtain trends estimates superconducting critical temperature agreement with experimental findings, which might identify universal
