cgnr

sisl.geom.cgnr(width, chirality, bond=1.42, atoms=None, vacuum=20.0)

Construction of an (n, m, w)-chiral graphene nanoribbon

Parameters:

width (int) – number of atoms in the transverse direction
chirality (tuple[int, int]) – index (n, m) corresponding to an edge with n zigzag segments followed by m armchair segments
bond (float) – C-C bond length
atoms (Optional[AtomsLike]) – atom (or atoms) in the honeycomb lattice. Defaults to Atom(6)
vacuum (FloatOrFloat2) – separation in transverse and perpendicular direction

Return type:
