sisl.geom.cgnr(width: int, chirality: tuple[int, int], bond: float = 1.42, atoms: sisl.typing.AtomsLike | None = None, vacuum: float | tuple[float, float] = 20.0) Geometry

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

Parameters:
  • width – number of atoms in the transverse direction

  • chirality – index (n, m) corresponding to an edge with n zigzag segments followed by m armchair segments

  • bond – C-C bond length

  • atoms – atom (or atoms) in the honeycomb lattice. Defaults to Atom(6)

  • vacuum – separation in transverse and perpendicular direction
