hcp
- sisl.geom.hcp(a: float, atoms: sisl.typing.AtomsLike, coa: float = 49 / 30, orthogonal: bool = False) float
Hexagonal closed packed lattice with 2 (non-orthogonal) or 4 atoms (orthogonal)
- Parameters:
a – lattice parameter for 1st and 2nd lattice vectors
atoms (
Atom
) – the atom(s) in the HCP latticecoa – c over a parameter where c is the 3rd lattice vector length
orthogonal – whether the lattice is orthogonal (4 atoms)
