1 Sep 2000 know the hierarchical system by which the symbol elements are assigned (cf. K ., p. 35). 6. Be familiar with the concept of Miller indices (K. p.
A generic Miller index is denoted by (hkl). If a plane has negative intercept, the negative number is denoted by a bar above the number. Never alter negative numbers. For example, do not divide -1, -1, -1 by -1 to get 1,1,1. This implies symmetry that the crystal may not have! Some General Principles. If a Miller index is zero, the plane is parallel to that axis. The smaller a Miller index, the more nearly parallel the plane is to the axis. The Miller-Bravais indices of a plane are denoted by h, k, i and l enclosed in parentheses, (h k i I). These indices are the reciprocals of intercepts on the a 1, a 2, a 3 and c-axes, respectively. As with Miller indices, the reciprocals are usually divided by the largest common factor.
c. Miller Indices Early in the 19th century W.H. Miller developed a system of crystal face notation which has many advantages over Weiss symbols. These symbols, called Miller indices, are simply the reciprocals of Weiss parameters, cleared of fractions, with the letters denoting the axes omitted. A face that has the Weiss symbol 3a:3b:1c.

In assigning Miller indices to the hexagonal lattice a redundant coordinate system is and planes in this system, but an additional (redundant) index is carried. Miller indices form a notation system in crystallography for planes in crystal lattices. In particular, a family of lattice planes is determined by three integers h, k, and ℓ, the Miller indices. They are written, and denote the family of planes orthogonal to h b 1 + k b 2 + ℓ b 3 {\displaystyle h\mathbf {b_{1}} +k\mathbf {b_{2}} +\ell \mathbf {b_{3}} }, where b i {\displaystyle \mathbf {b_{i}} } are the basis of the reciprocal lattice vectors. By convention, negative integers are Miller Bravais Indices Since the hexagonal system has three "a" axes perpendicular to the "c" axis, both the parameters of a face and the Miller Index notation must be modified. The modified parameters and Miller Indices must reflect the presence of an additional axis. Miller indices, group of three numbers that indicates the orientation of a plane or set of parallel planes of atoms in a crystal. If each atom in the crystal is represented by a point and these points are connected by lines, the resulting lattice may be divided into a number of identical blocks, or unit cells; This final manipulation generates the Miller Indices which (by convention) should then be specified without being separated by any commas or other symbols.
