Abstract:
We have investigated the structures of randomly and vertically oriented carbon nanotubes grown by thermal chemical vapour deposition and dual‐r.f.‐plasma‐enhanced chemical vapour deposition, respectively. The randomly oriented carbon nanotubes have a bamboo‐like structure, whereas the vertically oriented carbon nanotubes have a multi‐shell shape. Both types of nanotubes have a metal nanoparticle at the tip. The field emission property of the randomly oriented nanotube films was better than that of the vertically oriented nanotube films. This result indicates that more emission sites exist at the body than at the tip of the nanotubes. Copyright © 2003 John Wiley & Sons, Ltd.
