Miller indices form a notation system in crystallography for lattice planes in crystal (Bravais) lattices. In particular, a family of lattice planes of a given (direct) Bravais lattice is determined by three integers h, k, and ℓ, the Miller indices. They are written (hkℓ), and denote the family of (parallel) lattice planes (of the given Bravais lattice) o… Webcrystal. Lattice planes are indexed (hkl) according to their location within a unit cell. The indices are chosen such that the plane intersects the unit cell at three points a/h, b/k, and c/l. The indices [h k l] are known as the Miller indices. To calculate the Miller indices corresponding to a set of crystal planes: 1.
