Localized incorporation of lanthanum carbide crystals in carbon nanotubes


  • The authors would like to acknowledge Mr. R. Usui of JEOL Datum Ltd. for his kind help with the TEM observations.


Carbon nanotubes containing lanthanum carbide suggest that lanthanum may show catalytic activity for the formation of nanotubes. Images of the graphitic structures growing on the surface of silver-colored deposits such as the SEM image of a straight carbon nanotube shown in the Figure, are presented.
