| Research Abstract |
We have systematically studied the energetics, electronic structure, and geometries of various carbon nanotubes including chiral nanotubes from the first principles for the first time. We have clarified the presence of so-called family patterns in their energetics, electronic properties, and geometries. In addition, we have clarified the presence of the intrinsic twisting in chiral nanotubes, and opening the fundamental gap of graphene by introducing the periodic geometrical modification.
