WebFeb 21, 2024 · 1.2: Miller Indices (hkl) The orientation of a surface or a crystal plane may be defined by considering how the plane (or indeed any parallel plane) intersects the main crystallographic axes of the solid. The application of a set of rules leads to the assignment of the Miller Indices ( hkl ), which are a set of numbers which quantify the ...

WebMiller Indices are a 3-dimensional coordinates system for crystals, based on the unit cell. This coordinate system can betoken directions or flyers, and are often written as (hkl). Some common browse of Miller Key to a cube include [111], the body diagonal; [110], and face diagonal; and (100), the face plane. WebAug 12, 2024 · If the cubic lattice were rotated 90 , the a, b, and c directions would remain indistinguishable, and there would be no way of telling on which crystallographic positions the atoms are situated, so the family of directions is the same. In a hexagonal crystal, however, this is not the case, so the [100] and [010] would both be <100> directions ...
