Calculation of transport properties of Co-Ag-based multilayered granular alloys

Mostrar todas las versiones(2)

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-consisten...
