Resumen:
We calculate electronic transport properties of multilayered granular
alloys, composed of discontinuous Co layers embedded in Ag alternated
with complete Ag layers. We focus our attention on the conductivity
dependance on the shape and size of the clusters. The electronic
structure is self-consistently calculated using a tight binding
hamiltonian which includes a Hubbard term within the unrestricted
HartreeFock approximation. We obtain different transport regimes
depending on the growth conditions and transport direction.
