New method for single wall carbon nanotube growth — •Petr Nozar¹, Roberto Danieli², Viliam Vretenar¹, Riccardo Lotti², and Carlo Taliani^1,2 — ¹Istituto per lo Studio dei Materiali Nanostrutturati, CNR, Via P.

In the present contribution we report on a novel preparation method for Single Wall Carbon Nanotubes (SWCNT). The procedure is based on brand-new system of Pulsed Plasma Deposition (PPD) developed by Organic Spintronics, Srl. PPD for SWCNT growth represent a synthesis of methods based on a production of catalyst nanoparticles (nickel-cobalt) by plasma heating and CVD ones. The SWCNTs obtained by reported procedure are isolated (not in bundles) with very narrow distribution of diameters and almost free of amorphous carbon and graphite impurities.
