GTTubeParameters[n,m]
calculates the important geometric properties of single wall carbon nano tubes (n,m).
DetailsDetails
- Single wall carbon nanotubes are created by "rolling up" a part of a graphen layer. The corresponding graphene layer is characterized by the real space unit vectors The following properties are calculated:
- Chiral vector:
- Length of
- Diameter:
- Chiral angle:
- translational vector: , ,
- Length of
- Number of hexagons per unit cell:
- The symmetry vector is the site vector, having the smallest component in direction of . The vector consists of a rotation around the axis by an angle combined with a translation (pitch). Symmetry vector: .
- Pitch of :
- Rotation angle :
- Number of in :
- The following options can be given:
-
