Abstract

Atomic clusters formed by agglomeration of atoms constitute a new state of matter with novel properties which depend uniquely on their size, shape, dimensionality, and composition. If clusters could be designed in such a way that they can retain their structure when assembled into a material form, it is possible to envision a new class of solids with clusters as building blocks. These cluster-assembled materials would exhibit rather uncommon properties, thus enlarging the frontiers of material science. Self-consistent calculations have been carried out to study the effect of composition and geometry on the stability and reactivity of clusters. An understanding of the role that atomic and electronic structure play on cluster-cluster interaction would enable us to design cluster materials. This paper deals with the design guidelines, as well as properties of cluster-assembled crystals. It is shown that clusters designed to mimic the properties of known atoms can be viewed as superelements and thus help extend the limits of the current periodic table.
