graphene

sisl.geom.graphene(bond: float = 1.42, atoms: sisl.typing.AtomsLike = None, orthogonal: bool = False) → Geometry

Graphene lattice with 2 or 4 atoms per unit-cell, latter orthogonal cell

Parameters:

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

• atoms (Atom, optional) – the atom (or atoms) that the honeycomb lattice consists of. Default to Carbon atom.

• orthogonal (bool) – if True returns an orthogonal lattice

Return type:
