Recent advances in experimental techniques now enable researchers
to produce in a laboratory clusters of atoms of desired composition
from any of the elements of the periodic table. This has created a
new area of research into novel materials since clusters cannot be
regarded either as a "large" molecule or as a fragment of the bulk.
Both experimental and theoretical studies are revealing unusual
properties that are not ob served in solid state environments. The
structures of micro-clusters are found to be significantly
distorted from the most symmetric arrangement, some even exhibiting
pentagonal symmetry commonly found in icosahedric structures. The
unusual stability of certain clusters, now described as "magic
number species," shows striking similarities with the nuclear shell
structure. The relative stabilities of clusters depend not only on
the composition of the clusters but also on their charged states.
The studies on spontaneous fragmentation of mUltiply charged
clusters, commonly referred to as Coulomb explosion, illustrate the
role of electronic bonding mechanisms on stability of clusters. The
effect of foreign atoms on geometry and stability of clusters and
the interaction of gas atoms with clusters are showing promise for
an indepth understanding of chemisorption and catalysis. The
magnetic and optical properties are dependent not only on cluster
size but also on its geometry. These findings have the potential
for aiding industry in the area of micro-electronics and
catalysis."
