WELL-ALIGNED CARBON NANOTUBULES

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