Abstract

The alignment of carbon nanotubules greatly influences their transport properties, for example their electrical conductivity. Since these properties are important for potential applications in electronic devices, it is desirable to be able to control nanotube morphology during synthesis. An arc production method is presented that uses copper-mixed graphite as the positive electrode, resulting in the degree of alignment shown in the Figure.
