Notes on miller indices

Miller Indices can be used to describe directions Miller Index of a Crystal Orientation Note the loss of information in a diffraction experiment if each set of. Lecture Notes - Mineralogy - Miller Indices • All directions and planes in a mineral are referenced to a crystallographic coordinate system. This is always a right-handed coordinate system based on the unit cell of the mineral. 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 Miller indices specify not just one plane but an infinite set of equivalent planes. Note that for cubic crystals the direction [hkl] is perpendicular to a plane (hkl) having the same indices, but this is 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,

We will not go into the mathematics of Miller Indices, but rather take a Note that the “a” axis is labeled with a minus sign to indicate it is the back side of the “a”

Note that the distance between the planes drawn on each lattice (interplanar spacing) The Miller indices are generically represented by the triplet of letters hkl.

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.

HOW TO FIND MILLER INDICES. yDetermine the intercepts of the plane intersecting the xyz coordinate. a1 – x direction, a2 – y direction, and a3 – z direction. yTake the reciprocals of the intercepts. h = 1/a1, l = 1/a2, and m = 1/a3. yReduce the result to the smallest integer.

Miller indices are used to specify directions and planes. • These directions Notation Summary. • (h,k,l) represents a point – note the exclusive use of commas. 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 Lecture Notes - Mineralogy - Miller Indices. • All directions and planes in a mineral are referenced to a crystallographic coordinate system. This is always a

In the trigonal and hexagonal crystal systems, four-membered Bravais–Miller indices hkil are commonly used. Corresponding four-membered direction indices
