Construction of a graphene nanoribbon

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

  • bond – C-C bond length

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

  • kind – type of ribbon

  • vacuum – separation in transverse direction

  • chirality – index (n, m), only used if kind=chiral
