Miller Indices for Crystal Directions and Planes

Webdescribe lattice points (sites), directions and planes is known as Miller Indices. A crystal lattice may be considered as an assembly of equidistant parallel planes passing through the lattice points and are called lattice planes. In order to specify the orientation one employs the so called Miller 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 … WebMiller indices is a system of notation of planes within a crystal of space lattice. They are based on the intercepts of plane with the three crystal axes, i.e., edges of the unit cell. The intercepts are measured in terms of the edge lengths or dimensions of the unit cell which are unit distances from the origin along three axes. inclu maths symbole
