We calculate electronic transport property of multilayered granular alloys, composed by discontinuous Co layers embedded in Ag alternated with Ag layer. We focus our attention on the conductivity dependance on shape and size of the clusters. The electronic structure is selfconsistently calculated using a tight binding hamiltonian which includes a Hubbard term within the unrestricted Hartree Fock approximation. We obtain different transport regimes depending on growth conditions and transport direction.
