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
