graphene_flake
- sisl.geom.graphene_flake(shells: int, bond: float = 1.42, atoms: sisl.typing.AtomsLike = None, vacuum: float | tuple[float, float, float] = 20.0) Geometry
Hexagonal flake of graphene, with zig-zag edges.
- Parameters:
shells (int) – Number of shells in the flake. 0 means a single hexagon, and subsequent shells add hexagon units surrounding the previous shell.
bond (float) – bond length between atoms (not lattice constant)
atoms (sisl.typing.AtomsLike) – the atom (or atoms) that the honeycomb lattice consists of. Default to Carbon atom.
vacuum (float | tuple[float, float, float]) – Amount of vacuum to add to the cell on all directions
- Return type:
