| Research Abstract |
The effect of the orientational relationships(OR_s) between the graphite and the surface of catalytic metal nanoparticle on the chirality determination during growth process of single-walled carbon nanotubes(SWNT_s) is studied in this project. First, the interaction energy between graphene and nickel(111) surface with commensurate and incommensurate OR_s is examined. It is revealed that the hollow site structures, in which metal atoms are adjacent to hollow sites in graphene, give rise to global and local energy minima, respectively, whereas the interaction energy is almost constant for incommensurate structures. In addition, the cap structure of SWNT with definable chirality is obtained by hybrid molecular dynamics. Monte Carlo simulation.
