The low energy cluster beam deposition technique (LECBD) is used to produce nanostructured materials with original structures and properties. In this technique, clusters do not fragment upon impact on the substrate leading to the formation of granular films by nearly random stacking of incident clusters. Both nanostructured films and films of clusters embedded in various matrices are produced using this technique. The production and deposition of controlled size distributions of free clusters are briefly described as well as the specific nucleation and growth process characteristic of the LECBD. In the second part of the paper are presented some characteristic examples of novel materials prepared by this technique. The formation and properties of films of covalent materials (C, Si) and metallic materials (Fe, Co, Ni) are presented to emphasize the memory effect of the free cluster structure in the first case and the effect of the nanocrystalline film structure through the magnetic properties in the second case.
