Growth of carbon nanotubes (CNTs) was performed by atmospheric pressurechemical vapour deposition (APCVD) of propane on Si(111) with a pre-treated Nioverlayer acting as a catalyst. Prior to the growth of CNTs, a thin film of Niwas deposited on Si(111) substrate by evaporation and heat treated at900{\deg}C. The growth of nanotubes was carried out at 850{\deg}C using propaneas a source of carbon. Distribution of the catalyst particles over the Sisubstrate was analysed before and after heat treatment by atomic forcemicroscopy (AFM). The X-ray diffraction (XRD) pattern of the grown materialrevealed that they are graphitic in nature. Field emission scanning electronmicroscopy (FESEM) was used to investigate the growth process and it was foundthat a catalytic particle was always situated at the tip of the tube thusimplying a tip growth mechanism. Evidence for the presence of radial breathingmode from multi-wall nanotubes (MWNTs) in the grown sample was obtained frommicro-Raman analysis. Finally, high-resolution transmission electronmicroscopic (HRTEM) analysis confirmed that the graphene layers of the CNTs arewell ordered with typical 0.34 nm spacing.
