- Abstract
We studied SWCNTs and derivatives separated according to their metallicity using X-ray diffractometry, optical absorption, and Raman spectroscopy. The X-ray study evidences a complete absence of graphite and metal catalysts. Optical absorption shows that the metallic sample is of high purity, however, a small amount of metallic tubes are present in the semiconducting sample. We synthesized double-wall carbon nanotubes from the separated SWCNTs by filling-in C60's and heating these samples. The Raman spectra of the inner tubes are markedly distinct in the two types of samples and also allows to characterize the efficiency of the separation.
