A catalyst for single-wall carbon nanotube could be achieved by an agglomeration process of co-sputtered Co-Mo thin film on flat silicon wafers. Through the control of catalyst size and carbon flux, SWNTs and double-wall carbon nanotubes were synthesized. The addition of Mo in the Co catalyst makes an effective nucleation site for SWNT formation and the feeding of CH4 gas in chemical vapor deposition reaction keeps the suitable carbon concentration to grow a single-wall structure.
