Static polarizability of metal clusters and the related blue shift of the dipolar surface plasmon

Photon Emission Spectroscopy of Individual Oxide-Supported Silver Clusters in a Scanning Tunneling Microscope

“…The hybridization effect dominates the size dependence of the Mie-resonance position, thus explaining the pronounced blueshift. As expected, the corresponding a factor of 0.8 eV nm for this system [13] clearly exceeds the value for the supported Ag clusters in the present experiment. These considerations give only qualitative arguments for an understanding of the observed dependence of the Mie resonance on the cluster size.…”

“…A large number of measurements are available for ensembles of silver particles which are either supported on insulating surfaces (quartz [10], TiO 2 [11]) or embedded in weakly interacting matrices (glass [12], argon [13]). Various theoretical models have been developed to explain the experimental data [13][14][15]. In this paper we report photon emission spectra of individual oxide-supported Ag clusters as a function of size.…”

Interrelationship between structural, optical, electronic and elastic properties of materials

“…Self-consistent field theory has been used by Stern [8] to calculate the polarizability of a twodimensional electron gas. Static polarizability of metal cluster has been explained by Ekardt et al [9], using modified Thomas-Fermi approximation.…”

Formation of the Magic Cluster Na8 in Noble Gas Matrixes

“…The observation of several unique properties of clusters attracted the interest of scientists during the last 2 decades. − In particular, the appearance of their surprising size-dependent properties gave rise to the development of theoretical models incorporating these features. The first description of a self-consistent jellium model for clusters using a semiclassical density-variational method was reported by Cini in 1975 .…”
