honeycomb_flake

sisl.geom.honeycomb_flake(shells: int, bond: float, atoms: sisl.typing.AtomsLike, vacuum: float | tuple[float, float, float] = 20.0) → Geometry

Hexagonal flake of a honeycomb lattice, with zig-zag edges.

Parameters:

• shells – Number of shells in the flake. 0 means a single hexagon, and subsequent shells add hexagon units surrounding the previous shell.

• bond – bond length between atoms (not lattice constant)

• atoms – the atom (or atoms) that the honeycomb lattice consists of

• vacuum – Amount of vacuum to add to the cell in all directions (with tuple, individual vacuum lengths)
