Topological and Energetic Conditions for Lithographic Production of Carbon Nanotubes from Graphene

Figure 8

Simulation of zigzag nanotubes. The initial (a) and the final (b) structures are shown. The simulation parameters are the following: 1100 K simulation temperature, 13.53 Å and 15.99 Å of widths and 41.18 Å and 45.44 Å of lengths for the parallel nanoribbons. The distances between the atoms to be bonded are in order and at the zigzag and armchair sides of the ribbons.
