Abstract

The conductivity in a bilayer graphene in zero magnetic field is calculated within the self-consistent Born approximation. The bilayer graphene has a semi-metallic spectrum where the conduction and valence bands with k-square dispersions touch at the zero energy. We find that the quantum effect is significant around zero energy, where the conductivity becomes nearly universal, 2e22h̄ per spin, in a large disorder.
