چکیده مقاله :
Using DC- Plasma Enhanced Chemical Vapor Deposition (PECVD) system, the impact of pure Co on the growth of diamond-like carbon (DLC) nano-structures was investigated. In this study, Acetylene (C2H2) was diluted in H2 and used as the reaction gas and Co nano-particles were used as the catalyst. The effect of preparing Co catalyst on temperatures of 240ο C and 350ο C and growth conditions was studied. The results showed that the Co catalyst sputtering at 350ο-C temperature has a significant impact on purity, morphology, and synthesized diamond-like carbon nano- structures. This research was conducted to investigate the effect of catalyst preparation and growth conditions. Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy were used to characterize the diamond-like carbon nano- structures produced under different conditions.Using DC- Plasma Enhanced Chemical Vapor Deposition (PECVD) system, the impact of pure Co on the growth of diamond-like carbon (DLC) nano-structures was investigated.
