| Abstract: | Multi-walled carbon nanotubes (MWNTs) were synthesized on silicon substrates using nickel catalyst with thickness varied from 2 to 30 nm by microwave plasma chemical vapor deposition technique. The characterization results show that the diameter of produced MWNTs decreases with decreasing thickness of nickel catalyst layer. The MWNTs with narrow diameter of 8 nm have been obtained at the nickel catalyst thickness of 2 nm. |
