2 Nanotube Structure And Symmetry

Each single-walled nanotube can be viewed as a conformal mapping of the two-dimensional lattice of a single sheet of graphite (graphene), depicted as the honeycomb lattice of a single layer of graphite in Fig. 1, onto the surface of a cylinder. As pointed out by lijima l , the proper boundary conditions around the cylinder can only be satisfied if one of the Bravais lattice vectors of the graphite sheet maps to a circumference around the cylinder. Thus, each real lattice vector of the...

5 Conclusions

It is instructive to compare results from the various Raman scattering studies discussed in sections 4.2 nested nanotubes and 4.3 single-wall nanotubes . Ignoring small changes in eigenmode frequencies, due to curvature of the tube walls, and the weak van der Waals interaction between nested nanotubes, the zone-folding model should provide reasonable predictions for trends in the Raman data. Of course, the low-frequency telescope and rotary, shear-type modes anticipated in the range 30-50 cm1...
