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 …

Metal, metal oxide, and metal chalcogenide materials have a wide variety of applications.
For example, many metal clusters and nanoparticles are used as catalysts for reactions …

I begin this review with a statement that the socalled Jahn-Teller (JT) effect (hereafter JTE),
pseudo-JTE (PJTE), and Renner-Teller effect (RTE), jointly JT vibronic coupling effects, are …

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

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 …

Classification of the fragments which are obtained by successive division of material is given
according to their sizes. The particles are called fine particles when they consist of the order …

Over the past two decades methods have been developed to produce clusters with an
exactly determined number of atoms. Due to their finite size these small particles have totally …

Density functional calculations have been performed to study the structure and energetics of
mainly neutral Aln with n up to 153. Clusters up to n= 15 have been investigated …

Car-Parrinello molecular dynamics simulated annealings were carried out for clusters Si n,
Ge n, and Sn n (n<~ 1 3). We investigate the temperature regions in which these clusters …
