This article is published with open access at Abstract The application of plasma-enhanced chemical vapour deposition PECVD in the production and modification of carbon nanotubes CNTs will be reviewed. The challenges of PECVD methods to grow CNTs include low temperature synthesis ion bombardment effects and directional growth of CNT within the plasma sheath. New strategies have been developed for low temperature synthesis of single-walled CNTs based the understanding of plasma chemistry and modelling. The modification of CNT surface properties and synthesis of CNT hybrid materials are possible with the utilization of plasma. Keywords Plasma Carbon Nanotubes Ion bombardment Introduction Carbon nanotubes CNTs are unique one-dimensional carbon materials which exist mainly as single-walled SWNTs and multi-walled carbon nanotubes MWNTs . CNTs exhibit extraordinary properties such as high tensile strength excellent electrical and thermal conductivities 1 2 . A wide range of potential applications of CNTs have been envisioned in the field of computer logic and memory devices interconnect via nanosensors field emitters S. H. Lim Z. Luo J.

Of particular interest is the electronic property of SWNTs which are seamlessly rolled-up graphene sheets of carbon behaving either as semiconductors or as metals depending on its diameters and chiralities 11 . .
