This study reports the investigation on C₆₀ bombardment on the carbon nanotube (CNT) by molecular dynamic (MD) simulations. We found that carbon nanotube nanobuds or nanotube–fullerene hybrid nanostructures can be formed by C₆₀ bombardment. Different from the nanobuds in earlier studies, more structural patterns are found in the bombardment formed nanobuds and nanotube–fullerene hybrid nanostructures. In addition, the attaching strengths of the carbon nanobuds are explored, and results indicate that the junction between C₆₀ and CNTs in the nanobuds is very stable. Moreover, we also found that the bombardment formed nanobuds and nanotube–fullerene hybrid nanostructures generally decrease the maximum tensile strength and Young's modulus of carbon nanotubes.
