The SERS technique has been proved to be successful to study Single-Walled
Carbon Nanotubes (SWNT's), with the observation of peculiar features. In th
is study, we present more specifically the Raman features which are strongl
y dependent on the morphology of the nanotube thin films, their thickness,
the interfacial effects between films and support, the effect of solvent us
ed to disperse the nanotubes onto the metallic surface.
