GTTubeParameters
GTTubeParameters[n,m]
calculates the important geometric properties of single wall carbon nano tubes (n,m).
Details and Options
- Single wall carbon nanotubes are created by "rolling up" a part of a graphene 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

: 
- The following options can be given:
-
