摘要

It has been found that spherical large clusters of carbon atoms are formed by irradiation of crystalline C_(60) films grown on Si(111)-(7 × 7) surfaces with electrons field-emitted from a scanning tunneling microscope probe tip. The size distribution of the clusters deduced from surface profile measurements suggests that the dominant clusters were not necessarily C_(60n) (n = 2-4) expected from the simple fusion of C_(60) molecules. It was proposed that electronic excitations of C_(60) molecules caused the fragment and coalescence of the molecules to form the giant fullerenes as in the photo-induced similar effects.
