摘要
In this Letter, we provide conclusive evidence for a lattice like arrangement of the silver grains in the nanogranular Ag-Al2O3 metal. The evidence for the presence of clearly separated first and second near neighbor grains was derived from the electrical conductivity dependence on the metallic content in these composites. The data were analyzed in light of the tunneling percolation staircase model that we have recently suggested for lattices or systems with discrete well-defined interparticle distances in the continuum.
