The bundle structure and the sliding of single-walled carbon nanotubes (SWNTs) have been observed by frictional-force microscopy. The diameter of the nanotube and the nearest distance between any two nanotubes were estimated to be 1.4 and 0.3 nm, respectively. The frictional force required to move SWNTs on a KCl(001) surface and its energy dissipation were estimated to be 11 nN and 0.75x10[sup -16] J, respectively. © 2001 American Institute of Physics.

    Carbon nanofilaments are produced at 600 °C by catalytic decomposition of acetylene on palladium nanoparticles. We observe that nanofilament length is limited to a few hundreds of nm when the size of Pd germs is less than 10 nm, possibly due to the incorporation of Pd atoms during growth. We...
