    Notes: Abstract. Nanostructured carbon thin films have been grown by deposition of cluster beams produced by a supersonic expansion. Due to separation effects typical of supersonic beams, films with different nanostructures can be grown by the simple intercepting of different regions of the cluster beam with a substrate. Films show a low-density porous structure, which has been characterized by Raman and Brillouin spectroscopy. Film morphology suggests that growth processes are similar to those occurring in a ballistic deposition regime.

    Notes: Abstract Structure and stability of carbon clusters in the size range 50≤n≤72 have been investigated by means of a semiempirical many body potential (Tersoff, J.: Phys. Rev. Lett.61, 2879 (1988)). The ground state geometries, identified by Monte Carlo Simulated Annealing, may be described as slightly distorted hollow spheres, with nearly graphitic atomic arrangement. Starting from these structures, we simulate by Molecular Dynamics a series of cluster-cluster collisions. The final aim of these computations is to simulate the deposition of carbon clusters produced in a molecular beam on a graphite surface. Our preliminary results indicate that at leastC 60 could survive the deposition process.
