Abstract

In this paper, single-wall carbon nanotubes growth with the injection chemical vapour deposition method is presented. Ferrocene was dissolved in ethanol and such a solution was sprayed into a heated quartz tube reactor under Ar atmosphere. Raman spectroscopic studies using the intensity ratios between the D and G line reveal a very good crystallinity. The spectra display several lines in the low frequency region associated with the radial breathing mode. Based on our results the method presented appears to be more efficient than other more expensive methods like arc-discharge or laser ablation..
