So we understand pretty much how to label a plane using Miller indices. We now turn our attention to labeling a crystallographic direction with a Miller index. Let us label the “direction A” in the cubic unit cell on the right-hand side in Figure 2.11. For denoting directions, the direction must pass through the origin (O).

Crystallography: Miller Indices. Miller Indices are a symbolic vector representation for the orientation of an atomic plane in a crystal lattice and are defined as the reciprocals of the fractional intercepts which the plane makes with the crystallographic axes.. The method by which indices are determined is best shown by example. In the following four questions you are asked to identify a given plane in a lattice. The diagram shows unit cells for a cubic lattice.. Question 1. Click on the diagram that shows the plane (221) correctly drawn.
