ABSTRACT
Large-scale (∼109 atoms) numerical simulations reveal that plasma-controlled dynamic delivery and redistribution of carbon atoms between the substrate and nanotube surfaces enable the growth of ultralong single walled carbon nanotubes (SWCNTs) and explain the common experimental observation of slower growth at advanced stages. It is shown that the plasma-based processes feature up to two orders of magnitude higher growth rates than equivalent neutral-gas systems and are better suited for the SWCNT synthesis at low nanodevice friendly temperatures.

    This study focuses on the manufacture of carbon nanotubes using the arc discharge method. Several independent variables were changed, such as the current (80 and 100 A), an atmosphere of open air or argon and the catalyst (no catalyst, Fe or a mixture of Fe/Co,Ni). Only one set of parameters...
