| 摘要 |
The method of the present invention deposits carbon nanotubes by contacting carbon vapor with a non-magnetic transition metal including at least two elements selected from the group consisting of ruthenium, rhodium, palladium, and platinum. For example, carbon vapor and particulates of the non-magnetic transition metal are generated by arc discharge between a rod-shaped anode containing carbon and the non-magnetic transition metal, and a rod-shaped cathode opposing to the anode, and carbon nanotubes are deposited on a base portion of the cathode. The arc discharge is performed in a reactor chamber containing inert gas or the mixture of inert gas and hydrogen gas, at a pressure ranging from 50 to 1500 Torr.
