    In this work we investigate the growth of diamond film on a porous single-wall carbon nanotubes (SWNT) paper by employing three different systems: plasma-assisted hot filament, focused microwave plasma and linear antenna microwave plasma. We observe that the diamond growth is strongly affected by the different conditions in each of the CVD processes resulting in different SWNT/diamond structures. It is also found that only the linear antenna MWCVD process allows penetration of the activated growth species into the volume of the SWNT paper, whereas using the other methods, the diamond grains are formed on the SWNT surface only. Moreover, the growth of diamond within the substrate volume is strongly influenced by the CH4/CO2/H2 content ratio.
