goldene

sisl.geom.goldene(bond=2.7, atoms=None, orthogonal=False, vacuum=20.0)[source]

A goldene unit-cell with 1 or 2 atoms in the basic unit cell

Parameters:

bond (float) – bond length between atoms (not lattice constant)
atoms (Atom, optional) – the atom (or atoms) that the hexagonal lattice consists of. Default to Gold atom.
orthogonal (bool) – if True returns an orthogonal lattice (2 atoms), otherwise a non-orthogonal lattice (1 atom).
vacuum (float) – length of vacuum region (along 3rd lattice vector)

Return type:
