Field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), Raman spectroscopy, and reflection high-energy electron diffraction (RHEED) have been used to study samples grown for various deposition times. The information achieved by combined use of these characterization techniques has enabled the construction of a time-growth sequence for the two carbon nanophases and has enlightened the peculiar growth of such hybrid carbon systems. The tubular inner structures are found to be bundles of single-walled carbon nanotubes (SWNT) up to 15 ím long, and the outer deposits consist of wellshaped diamond crystallites with diameters in the 20-100 nm range.
