Metal spherical nanostructures and dielectric response quantum-size effects in silver nanoclusters

Abstract

The change of the quantum dielectric response of metal clusters has been investigated by tuning their size and topology. In order to calculate the change, analytical and numerical methods have been used. Results are presented for silver metal spheres. We have discussed possible ways for the experimental verification on the basis of scanning tunneling spectroscopy (STM) (Limot et al. 2005) or electron energy loss spectroscopy (EELS) (Eccles et al. 2010).
