Based on the structural peculiarity of two-layer graphene, which consists of translational and energetic nonequivalency of carbon atoms from different sublattices, it is shown that the density of long-wave electronic states at the Fermi level is finite (in contrast to the graphene monolayer). It is suggested that may be the reason why the critical temperature of the superconducting transition in multiwall nanotubes is more than ten times higher than in single-wall nanotubes.
