graphene¶

sisl.geom.graphene(bond=1.42, atom=None, orthogonal=False)[source]¶

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

Parameters:

bond : float

bond length between atoms (not lattice constant)

atom : Atom, optional

the atom (or atoms) that the honeycomb lattice consists of. Default to Carbon atom.

orthogonal : bool, optional

if True returns an orthogonal lattice
