nanoribbon

sisl.geom.nanoribbon(width, bond, atoms, kind='armchair', vacuum=20.0, chirality=(3, 1))

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

The geometry is oriented along the $x$ axis.

Parameters:

width (int) – number of atoms in the transverse direction
bond (float) – bond length between atoms in the honeycomb lattice
atoms (AtomsLike) – atom (or atoms) in the honeycomb lattice
kind (Literal['armchair', 'zigzag', 'chiral']) – type of ribbon
vacuum (FloatOrFloat2) – separation in transverse and perpendicular direction
chirality (tuple[int, int]) – index (n, m), only used if kind=chiral

Return type:
