## Abstract

The Kubo formula for the electrical conductivity of per stratum of few-layer graphene,
up to five, is analytically calculated in both simple and Bernal structures within the
tight-binding Hamiltonian model and Green's function technique, compared with the single-layer one. The results show that, by increasing the layers of the graphene as well
as the interlayer hopping of the nonhybridizedp
z orbitals, this conductivity decreases.
Although the change in its magnitude varies less as the layer number increases to beyond two,distinguishably, at low temperatures, it exhibits a small deviation from linear
behavior. Moreover, the simple bilayer graphene represents more conductivity with respect to
the Bernal case.
