sisl.geom.nanoribbon(width: int, bond: float, atoms: AtomsLike, kind: Literal['armchair', 'zigzag', 'chiral'] = 'armchair', vacuum: FloatOrFloat2 = 20.0, chirality: tuple[int, int] = (3, 1)) → Geometry

Construction of a nanoribbon unit cell of type armchair, zigzag or (n,m)-chiral.

The geometry is oriented along the \(x\) axis.

Parameters:

• width – number of atoms in the transverse direction

• bond – bond length between atoms in the honeycomb lattice

• atoms – atom (or atoms) in the honeycomb lattice

• kind – type of ribbon

• vacuum – separation in transverse and perpendicular direction

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