Cluster-assembled carbon films with different nanostructures: a spectroscopic study

Carbon thin films with different nanostructures grown by Cluster Beam Deposition are studied by means of Raman Spectroscopy, X-ray photoemission spectroscopy (XPS), and electron energy loss spectroscopy (EELS). Raman and EELS of the as-grown specimens show a correlation between the properties of the free carbon clusters and the properties of the films obtained by deposition of different sized clusters. In contrast, the inhomogeneous character of the films is not reflected in the valence band states as seen by XPS.
