Graphite lattice, with carbon nanotubes

Sliding between concentric multiwalled carbon nanotubes presents a simple geometry, which restricts interlayer motion to a single (axial) direction with a fixed interlayer orientation of stiff, smooth layers. Each layer in a concentric multiwalled carbon nanotube is indexed by two integers (n, m) that give the circumference in graphitic lattice coordinates. The difference in radii between successive layers frustrates the circumferential interlayer registry. The axial... 

Figure A. 11a shows a schematic image of the atomic structure of graphite plane - graphene, and shows how from it can be obtained the nanotube. The nanotube is fold up with the vector connecting two atoms on a graphite sheet. The cylinder is obtained by folding this sheet so that were combined the beginning and end of the vector. That is, to obtain a carbon nanotube from a graphene sheet, it should turn so that the lattice vector R has a circumference of the nanotube in Fig. A. 11b. This vector can be expressed in terms of the basis vectors of the elementary cell gra-...
