Construction of a graphene nanoribbon
- Parameters:
width (int) – number of atoms in the transverse direction
bond (float) – C-C bond length
atoms (Optional[AtomsLike]) – atom (or atoms) in the honeycomb lattice. Defaults to
Atom(6)kind (Literal['armchair', 'zigzag', 'chiral']) – type of ribbon
vacuum (FloatOrFloat2) – separation in transverse direction
chirality (tuple[int, int]) – index (n, m), only used if
kind=chiral
- Return type:
