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.

Mentions: Kato et al. [57] studied the kinetics of reactive ion etching on the synthesis of SWNTs in a parameter-controlled PECVD reactor. Figure 8 showed the time evolution of the graphitization of SWNTs synthesis due to reactive ion-etching effects. The growth kinetics of SWNTs was monitored using Raman spectroscopy whereby the degree of graphitization of SWNTs was assumed to be related to its tangential mode (IG). For weak and negligible ion etching, the growth kinetics of SWNTs in a PECVD method at 750°C was very similar to a thermal CVD process, which can be expressed as follow:
