Abstract:Transmission electron microscopy (TEM) images demonstrate that two graphitic nanoparticles, a nanoparticle and a nanotube, as well as two nanotube pairs can join together under specific angles in bump-like, neck-like and L patterns with saddle surfaces at the junction. A negatively curved surface containing eight-member rings has first been observed in the L type structure. It is suggested that the large energy transfer of the proton-carbon collision plays an important role in forming such structures.
