A Molecular Dynamics Study of Silicon Clusters
The structural properties of neutral and charged silicon clusters of moderate size were obtained from a molecular dynamics simulation using Stillinger-Weber model potential [Phys.Rev.B 31,5262(1985)]. Cluster equilibrium configurations resulting from quenches initiated at finite temperatures and ended at low temperatures established different growth sequences for neutral and charged clusters. Cooling and heating experiments were carried out showing that the transition from liquid-like systems to solid-like structures is very smooth. A model of an amorphous five layer film is constructed using the 14-atom cluster as elemental building block.
