Atomic clusters, consisting of a few to a few thousand atoms, have emerged over the past 40
years as the ultimate nanoparticles, whose structure and properties can be controlled one …

The structural properties of free nanoclusters are reviewed. Special attention is paid to the
interplay of energetic, thermodynamic, and kinetic factors in the explanation of cluster …

Silicon is the most important semiconducting material in the microelectronics industry. If
current miniaturization trends continue, minimum device features will soon approach the …

Highly crystalline, size-selected silicon (Si) nanocrystals in the size range 2–10 nm were
grown in inverse micelles and their optical absorption and photoluminescence (PL) …

We demonstrate that electrochemically etched, hydrogen capped Si n H x clusters with n
larger than 20 are obtained within a family of discrete sizes. These sizes are 1.0 (Si 29), 1.67 …

Abstract Using the Car-Parrinello method, we have obtained unforeseen structures for the
low-lying isomers of Si 45 and other midsized Si clusters. They are formed by two shells of …

Ab initio all-electron molecular-orbital calculations have been carried out to study the
structure and relative stability of small silicon clusters (Si n, n= 7–11). A number of low …

Variational and fixed-node diffusion Monte Carlo methods are applied to study the structural
and valence electronic properties of Si n clusters. Binding energies for n≤ 7 agree within≈ …

Injected ion drift tube techniques have been used to probe the geometries of germanium
cluster ions. Clusters with∼(10-40) atoms appear to follow a one-dimensional growth …

Structure and electronic properties of neutral and cationic pure and Ni-doped Ge clusters
containing 1− 20 Ge atoms are calculated within the framework of linear combination of …
