| We study the problem of electronic transport in graphene multilayers taking into account disorder scattering. We find that the electronic behavior of multi-layer deviates strongly from Landau Fermi liquid theory. We show that unitary scattering, treated in a self-consistent way, produces divergences in the electronic density of states leading to short quasiparticle lifetimes and large broadening of angle resolved photoemission (ARPES) lines. We show that the out-of-plane transport is enhanced by disorder in neutral graphene and that the anisotropy ratio between in-plane and out-of-plane transport is huge at low temperatures. These properties characterize graphene multi-layers in a different class of (chiral) systems where Landau's Fermi liquid theory is violated. |
