Lattice defects and electronic properties of graphene

ORAL

Abstract

We analyze the electronic properties of graphene. Extended lattice defects, and deviations from electron-hole symmetry, lead to self doping, and to a finite Fermi surface. Point lattice defects give rise to a finite inverse elastic lifetime at low energies, and to a universal value of the dc conductivity at low frequencies or temperatures. Transport properties at optical frequencies are also investigated.
