Crystal lattice planes

Vectors and planes in a crystal lattice are described by the three-value Miller indexnotation. This syntax uses the indices h, k, and ℓas directional parameters. [4] By definition, the syntax (hkℓ) denotes a plane that intercepts the three points a1/h, a2/k, and a3/ℓ, or some multiple thereof.
