▪ Abstract The strict criterion for metallicity, a finite density of states (DOS) at the Fermi
energy (EF), cannot be applied to clusters because energy levels are always discrete in a …

Thin-film materials, normally considered metals, can exhibit behavior that is very
nonmetallic. There is an increasing body of experimental information that this phenomenon …

Clusters as mesoscopic particles represent an intermediate state of matter between single
atoms and solid material. The tendency to miniaturise technical objects requires knowledge …

Structural and electronic properties of neutral and anionic magnesium clusters with 2 to 22
atoms are studied using gradient-corrected density functional theory. A new scheme for the …

We have measured the photoelectron spectra of mass-selected negatively charged mercury
clusters Hg n− in the size range n= 3–250. The spectra are characterized by gaps which …

We have characterized the structures of Sn n cations up to n= 68 using ion mobility
measurements. Up to n∼ 3 5, tin clusters track the prolate growth pattern previously found …

Optical absorption spectra for mass-selected Hg n+ and Hg n++ clusters show an abrupt
transition to a collective, plasmonlike absorption as a function of increasing cluster size. The …

Characteristic properties as well as possible differences in bonding of small group 12
clusters (, Cd, Hg;) have been investigated by quantum chemical ab initio methods, ie …

A comprehensive study of small mercury clusters is presented using relativistic coupled
cluster, many-body perturbation, and density functional theory starting from the dimer …

Electron-nuclear relaxation dynamics are studied in Hg n−(11⩽ n⩽ 16, n= 18) using time-
resolved photoelectron imaging. The excess electron in the anion uniquely occupies the p …
