Single-walled carbon nanotubes (SWNTs) are synthesized from iron silicide (FeSi) catalyst by the chemical vapor deposition (CVD). During the growth process, Fe atoms migrate onto the FeSi surface and form active Fe nanoparticles, catalyzing the growth of SWNTs. The produced SWNTs demonstrate a n...
