Calculation of electron density of states for ensemble of gold nanoclusters

Abstract

The method was developed for calculation of electronic properties of an ensemble of nanoclusters with the use of cluster perturbation theory. This method was applied to the ensemble with various geometry of gold nanoclusters with octahedral symmetry. The dependence of the density of electronic states on the mutual spatial arrangement of nanoclusters in the ensemble is obtained. It is shown that the metallic behavior of the ensemble maintains even when strong disorder is present.
