| Outline of Final Research Achievements |
The mechanical properties of graphene nanostuctures are investigated using molecular-dynamics simulation. It is revealed that the number and amplitude of wrinkles of a graphene nanoribbon under shear deformations depend on the width of the graphene nanoribbon and on the magnitude of the shear deformations, that the morphology of a graphene nanoribbon encapsulated in a single-walled carbon nanotube is determined by the difference between the diameter of the carbon nanotube and the width of the nanoribbon, and that the in-plane shear and tensile deformations of pillared graphene depend on the diameter of a carbon nanotube as a pillar. These findings will be utilized as basic data when graphene nanostructures are applied to nanodevices.
