Abstract

A new technique for single-wall carbon nanotube (SWNT) synthesis by simultaneous deposition of C60 and cobalt is reported. A study of Co + C60 mixture films by high-resolution transmission electron microscopy (TEM) revealed an existence of SWNTs even at room temperature. Thus, carbon nanotubes filled by some atomic row have been found nearby C60 polymeric chains. Within amorphous carbon region the smallest nanotube with a diameter of 0.4nm has also been observed as a continuation of filled SWNT. Analysis of Raman spectra discovered an intense growth of SNWTs in the mixture after annealing at 300°C. Based on TEM and Raman experiments, the conversion of Co-C60 polymeric chains into Co-filled SWNTs is discussed.
