Özet
In this paper, cobalt and nickel NPs (nanoparticles) effect on carbon nanotubes growth by Thermal chemical vapor deposition (TCVD) is studied. The DC - sputtering system was used to prepare cobalt and nickel thin films on Si substrates. The produced layers were used as metal catalysts for growing carbon nanotubes (CNTs) from acetylene (C2H2) gas in the temperature range of 850°C to 1000°C with an interval of 50°C by Thermal Chemical Vapor Deposition (TCVD) technique. Energy Dispersive X-ray (EDX) measurements were used to investigate the elemental composition of the cobalt and nickel NPs deposited on the Si substrates. Also, Atomic Force Microscopy (AFM) was used to characterize the surface morphology of the Co and Ni nanoparticles on the Si substrates. The grown CNTs on the Co and Ni catalyst at different temperatures have been characterized by Raman spectroscopy, Field Emission Scanning Electron Microscopy (FESEM) and High Resolution Transmission Electron Microscopy (HRTEM). The results showed that the diameter of CNTs can be controlled by adjusting the growth temperature, and increasing the temperature leads to increasing the diameter of CNTs. It was found that there is a strong relation between diameter and yield of CNTs at different growth temperature with different catalysts (Co and Ni). Also, the grown CNTs at the temperature of the 850°C using Co catalyst among all of the samples (Co and Ni catalysts) have a minimum diameter and maximum yield.
