Miller Indices for Directions •A vector r passing from the origin to a lattice point can be written as: r = r 1 a + r 2 b + r 3 c where, a, b, c → basic vectors and miller indices → (r 1 r 2 r 3) •Fractions in (r 1 r 2 r 3) are eliminated by multiplying all components by their common denominator. •[e.g. (1, ¾ ,½ ) will be expressed as (432)] Thus, the Miller indices are 3,6,2. If a plane is parallel to an axis, its intercept is at infinity and its Miller index is zero. 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. 6. All the parallel equidistant planes have the same Miller indices. Thus the Miller indices define a set of parallel planes. 7. A plane parallel to one of the coordinate axes has an intercept of infinity. 8. If the Miller indices of two planes have the same ratio (i.e., 844 and 422 or 211), then the planes are parallel to each other. 9. 30 Miller Indices Reciprocal numbers are: 2 1 , 2 1 , 3 1 Plane intercepts axes at cba 2,2,3 Indices of the plane (Miller): (2,3,3) (200) (100) Indices of the direction: [2,3,3]a 3 2 2 b c [2,3,3] Z X Y (100) Z X Y (110) Z X Y (111) 31. 31 Example 7 31 32. 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 8. MILLER INDICES FOR DIRECTIONS • Draw vector, and find the coordinates of the head, h1,k1,l1 and the tail h2,k2,l2. • subtract coordinates of tail from coordinates of head • Remove fractions by multiplying by smallest possible factor • Enclose in square brackets 9. Multiplying each by , we get 1,1,2. Hence the Miller Indices of the plane are (112) Important Features of Miller Indices. When a plane is parallel to any axis, the intercept of the plane on that axis is infinity. Hence The Miller Indices for that axis zero. If a plane cuts an axis on the negative side of the origin, corresponding index is negative.

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 Miller Indices. Rules for Miller Indices: Determine the intercepts of the face along the crystallographic axes, in terms of unit cell dimensions. Take the reciprocals 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 2 Jun 2016 Miller Indices for a crystallographic crystal.

Notes on Miller Indices 13:58 No comments: The crystal lattice may be regarded as made up of an infinite set of parallel equidistant planes passing through the lattice points which are known as lattice planes. The components of r along the three axes are- n 1 = 4, n 2 = 4 and n 3 = 0. Then the crystal direction denoted by ‘r’ is written as [440] in Miller notation, with square brackets enclosing the indices. If we clear the common factor, we can represent the same direction by [110] in Miller notation, Miller Indices for Directions •A vector r passing from the origin to a lattice point can be written as: r = r 1 a + r 2 b + r 3 c where, a, b, c → basic vectors and miller indices → (r 1 r 2 r 3) •Fractions in (r 1 r 2 r 3) are eliminated by multiplying all components by their common denominator. •[e.g. (1, ¾ ,½ ) will be expressed as (432)] Thus, the Miller indices are 3,6,2.
