In this paper the specific properties of free clusters and the formati
on of new cluster-assembled materials using the low energy cluster bea
m deposition (LECBD) technique are discussed. Recent results obtained
for free clusters are summarized with special attention to new observe
d structures. As for the specific structures and properties of cluster
-assembled materials, two main aspects are specially emphasized : the
memory effect of the free cluster properties leading to the formation
of new phases and the effect of the specific nanostructure of the clus
ter-assembled materials related to the random cluster stacking mechani
sm characteristic of the LECBD. These effects and the corresponding po
tential applications are illustrated using some selected examples : ne
w diamond-like carbon films produced by fullerene depositions (memory
effect) and grain effect on the magnetic properties of cluster-assembl
ed transition metal films.
