Four digit Miller index is sometimes used for hexagonal lattices. The idea is to have useful property: permutation of indexes gives an equivalent direction. It is mentioned in wikipedia, by the way. So you could start from there. Four-digit Miller indexes are never used for cubic structure.

Millersche Indizes dienen in der Kristallographie der eindeutigen Bezeichnung von Kristallflächen bzw. Ebenen im Kristallgitter. Die Schreibweise wurde im Jahr 1839 von William Hallowes Miller vorgeschlagen. In der gleichen Arbeit führte Miller auch die heute gebräuchlichen Schreibweisen für Richtungen und {hkl} für Kristallformen, d. h. die Menge aller symmetrisch äquivalenten Flächen, ein.

The result is written in the form (hkl) and is called the Miller Indices of the plane. Example. Let the plane have intercepts 4, 1 and 2 on the three axes. The reciprocals are ¼ , 1 and ½. Multiplying each by 4, we get 1, 4 and 2.

4" " 2. Stacking Faults and Miller Indices Lattice defects play an important role in determining the physical properties of crystalline solids. Derive the zone law for Miller-Bravais (4-index) indices using the zone law for Miller (3-index) indices and the transformation relations determined in class.

Solution. The directions asked for are indicated in the cubic unit cells shown below. Determine the Miller indices for the planes shown in the following unit cell:. Position vector for any non-reticular point of a direct lattice. where x, y, z The Miller indices are generically represented by the triplet of letters hkl.

Orientation of a crystal plane in a lattice is specified by Miller Indices. These are denoted as h,k & l (the plane is denoted as (hkl) ). These are defined as the reciprocal of the intercepts by the plane on the axes. This is an online tool to visualise a plane associated with a specific set of miller indices.

Obligationen ges ut inom ramen för Miller-Bravais indices With hexagonal and rhombohedral lattice systems, it is possible to use the Bravais-Miller system, which uses four indices (h k i ℓ) that obey the constraint h + k + i = 0. Here h, k and ℓ are identical to the corresponding Miller indices, and i is a redundant index.

Hence the Miller Indices of the plane are (112) How to find Miller Indices: To determine the indices for the plane p in Figure 2, -first we have to find the intercepts with the axes along the basis vector a,b,c. Let these intercepts be x, y, z. We form the fractional triplet c z b y a x,. -Take reciprocal to this set. We can found miller indices by following process.
