Abstract
Carbon nanotubes were prepared using a transition metal catalyst and alcohol carbon source. After putting a small amount of a solution of ethanol and ferric chloride on one end of a Si (100) substrate, the substrate was heated in a furnace, first under a flowing gas mixture of argon and hydrogen and thereafter under a flowing gas miture of argon, hydrogen, and ethanol. The product included semiconducting and metallic type carbon nanotubes. Scanning electron micrograph images demonstrated that the product included carbon nanotubes that were about as long as the substrate (about 4 cm), suggesting that even longer carbon nanotubes would result if an even longer substrate was used.
