Abstract
In the present study, single wall carbon nanotubes (SWCNTs) have been successfully grown on Fe based catalyst silicon substrate. The plasma enhanced chemical vapor deposition (PECVD) technique has been used to grow single wall carbon nanotubes (SWCNTs). The Fe catalyst has been deposited by RF–sputtering technique. The thickness of deposited catalyst layer is in a few nanometer range. The catalyst play a great role in controlling the diameter distribution of SWCNTs. The hydrogen was used for the pretreatment of the iron deposited catalyst substrate. The acetylene was used as the carbon source gas. The growth temperature and time has been kept 6500C and 10 min respectively. As per the requirement, parameters have been optimized accordingly. The obtained SWCNTs have been characterized and properly investigated by various techniques like FESEM with EDAX, HRTEM, and Raman spectroscopy.
