Abstract:

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 Hartree-Fock approximation. We obtain different transport regimes depending on the growth conditions and transport direction. © 2002 Elsevier Science B.V. All rights reserved.
