Abstract

In the present work we report the growth of icosahedral, decahedral and single faulted carbon particles by heating carbon soot with 3.4 wt% of C₆₀-C₇₀. The heating was carried out at ~730°C during 45 min in a vacuum of 10^-5 Pa. The carbon particles were identified using high resolution transmission electron microscopy (HREM) and electron energy loss spectroscopy (EELS). It was found that the five-fold structures are similar to those observed in metals but with a larger degree of disorder. High resolution images of the decagonal particles clearly show heptagonal rings of atoms. The existence of five-fold symmetry structures in carbon such as the icosahedron and decahedron adds a new interesting family of carbon structures in addition to the buckyballs and buckytubes.
