Abstract: (1870 Views)
Single wall carbon nanotubes were synthesized using laser ablation method in vacuum. A high power Ce:Nd:YAG laser was used for this goal. FESEM microscopy showed the formation of high pure carbon nanotubes. Moreover, the small amount of D to G intensity in Raman spectrum and the existence of RBM mode show the formation of semiconductor SWNTs. The diameter of SWNTs was calculated using the wavenumber of RBM mode in Raman spectrum. The results showed that SWNTs are 1/3 nm in diameter that TEM microscopy conforms it.
