摘要：
It is shown that, during electron irradiation of a thin carbon film in the presence of gold nanoparticles, fullerene onion structures are produced at a much higher rate than in the case in which no nanoparticles are present. We conclude that steps on the gold nanoparticle act as catalytic sites to promote the rearrangement of carbon atoms into caged structures. Once being nucleated, onion structures are ejected from the surface.
