Crystal indices
WebMiller Indices are a 3-dimensional coordinate system for crystals, based on the unit cell. This coordinate system can indicate directions or planes, and are often written as (hkl). Some common examples of Miller Indices on a … WebAll lattice planes and lattice directions are described by a mathematical description known as a Miller Index. This allows the specification, investigation, and discussion of specific planes and directions of a crystal. In the cubic lattice system, the direction [hkl] defines a vector direction normal to surface of a particular plane or facet.
