Abstract

We present STM results on single wall carbon nanotubes (SWCNTs), purified using weakly ionized and highly dissociated hydrogen plasma. The results show that, the purification process is successful in detaching the catalytic metallic particles from the SWCNT ropes. Within individual SWCNT rope we find that the metallic components are highly defective and dramatically shortened, while the semicoducting ones are with little or no defects. The defect states cause a multiple scattering of electron waves and appear as a bright spots in high‐resolution STM images.
