Iron nanoparticles derived from iron-complexed polymethylglutarimide to produce high-quality lithographically defined single-walled carbon nanotubes

A method of generating iron nanoparticles derived from an iron-complexed polmethylglutarimide (PMGI) to produce high-quality lithographically defined single-walled carbon nanotubes (SWCNT) was described. After the removal of all the organic components, uniformly distributed ion particles with reasonably controlled size were produced. It was found that complexation reaction is essential to obtain small and yet high-density nanoparticles. It was shown that the system in which iron nitrate is complexed with PMGI produces the most uniform iron oxide nanoclusters.
