Growth of Carbon Nanotubes on Silicon Substrate and Nickel Catalyst by Thermal CVD using Ethanol

In this research, carbon nanotubes were grown through thermal chemical vapor deposition. Argon, ethanol vapors, and nickel deposited on silicon substrate were used as a carrier gas, carbon source, and catalyst, respectively. The experiment was performed in atmospheric pressure at 650, 750, and 850 C for 15 minutes and the impact of temperature on the growth of carbon nanotubes was studied. The synthesized Nanotubes were examined by a scanning electron microscope and Raman spectroscopy.
