| Research Abstract |
I investigated the variations of the crystal structure and the electronic structure of the carbon nanotubes by the plastic deformation. About the crystal structure : It is found that the activation energy for the deformation decreases when there exists apparent defect in the nanotube. The possible reason is that the energy for the C-C bond switching decreases when there exists defect in the nanotube. About the electronic structure : It is found that the electric conduction decreases with the bending angle increasing in the plastic deformation process. The possible reasons are that(1) the introduction of the defect in the bending position which results in the electron scattering center,(2) the formation of the sp^3-like bonding by the bending, and(3)б-πhybridization.
