A new technique of synthesizing single-walled carbon nanotubes (SWNTs) directly on the surface of Si and quartz substrates is introduced in this report. This technique adopted a liquid based dip-coat method to mount very small amount of catalyst metals on the surface of the substrates with using Mo/Co bimetallic acetate solution. Merits of this approach lie in its easy, costless, and geometry-flexible nature compared with conventional sputtering and deposition approaches. We used alcohol catalytic CVD (ACCVD) method that can produce relatively high quality SWNTs even at low temperature down to 600℃. This low temperature process contributes to the prevention of agglomeration of catalytic metals on the surface and chemical reaction between catalytic metal and silicon, which helps us to eliminate any kind of intermediating support materials. Thereby synthesized SWNTs on Si and quartz substrates under various CVD conditions are characterized by means of SEM, TEM, Raman scattering, and optical absorbance measurements. The underlying reasons of why our experimental procedure and choice of catalyst worked for the synthesis of SWNTs are discussed through comparative studies. In the end of this report, some possible application of this technique is stated.
