Crystal Directions and Miller Indices

08 Jun 2010 | Teaching Materials | Contributor(s): David K. Ferry, Dragica Vasileska, Gerhard Klimeck

Miller indices are a notation system in crystallography for planes and directions in crystal lattices. In particular, a family of lattice planes is determined by three integers, l, m, and n, the Miller indices. They are written (lmn) and denote planes orthogonal to a direction (l,m,n) in the basis …
