nanotube

sisl.geom.nanotube(bond, atom=None, chirality=(1, 1))

Nanotube with user-defined chirality.

This routine is implemented as in ASE with some cosmetic changes.

Parameters:

bond: float

length between atoms in nano-tube

atom: Atom(6)

nanotube atoms

chirality: (int, int)

chirality of nanotube (n, m)
