•Miller indices are used to specify directions and planes. •These directions and planes could be in lattices or in crystals. •The number of indices will match with the dimension of the lattice or the crystal. •E.g. in 1D there will be 1 index and 2D there will be two indices etc

• DETERMINATION OF 'MILLER INDICES • Step 1:The intercepts are 2,3 and 2 on the three axes. • Step 2:The reciprocals are 1/2, 1/3 and 1/2. • Step 3:The least common denominator is '6'. Multiplying each reciprocal by lcd, we get, 3,2 and 3. • Step 4:Hence Miller indices for the plane ABC is (3 2 3) 14 Miller indexes (hkl) are constructed in such a way that reciprocals of the intersect points are taken. Thus, in the case of Figure 1.2(a), the Miller indexes (hkl) are a/a, a/∞,a/∞ or (100). If the plane intercept points would be ½ a,∞,∞, Miller indexes of that plane would be (200)

Concept of Miller Indices: Miller indices is a system of notation of planes within a crystal of space lattice. They are based on the intercepts of plane with the three crystal axes, i.e., edges of the unit cell. The intercepts are measured in terms of the edge lengths or dimensions of the unit cell which are unit distances from the origin along three axes. Procedure for finding miller indices
ed 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.

Prof William Hallowes Miller FRS HFRSE LLD DCL (6 April 1801 - 20 May 1880) was a Welsh mineralogist and laid the foundations of modern crystallography. Miller indices are named after him, the method having been described in his Treatise on Crystallography (1839). The mineral known as millerite is named after him See Article History. 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; the intersecting.

English: The Miller indices are a notation used to describe lattice planes and directions in a crystal. Deutsch: Die Millerschen Indizes sind eine Notation, die verwendet wird um Ebenen und Richtungen in Kristallen zu beschreiben. Miller Index 111 The law of rational indices states that the intercepts, OP, OQ, OR, of the natural faces of a crystal form with the basis vectors OA = a, OB = b, and OC = c are inversely proportional to prime integers, h, k, l, called Miller indices of the face Miller Indices are a method of describing the orientation of a plane or set of planes within a lattice in relation to the unit cell. They were developed by William Hallowes Miller

De miller-index of millerindex is de oriëntatie van een kristalvlak ten opzichte van het kristalrooster. Millerindices fungeren dus als een afkorting van de vlakvergelijking. De Miller-indices werden in 1839 geïntroduceerd door de Britse mineraloog William Hallowes Miller. Method 密勒指数 (Miller indices)是一种用来描述某一种晶格点阵 (布拉菲格子)中某一晶面族的数组。 Millersche Indizes dienen in der Kristallographie der eindeutigen Bezeichnung von Kristallflächen bzw. Ebenen im Kristallgitter. Die Schreibweise (hkl) wurde im Jahr 1839 von William Hallowes Miller (1801-1880) vorgeschlagen. In der gleichen Arbeit führte Miller auch die heute gebräuchlichen Schreibweisen [uvw] für Richtungen (Richtungsindizes) und {hkl} für Kristallformen, d. h. die.

A Miller-indexek a kristálytanban alkalmazott jelölésrendszer elemei, mellyel rácssíkokat, rácsirányokat adhatunk meg. A Miller-indexeket William Hallowes Miller javasolta 1839-ben. Például egy háromdimenziós rácsban egy párhuzamos rácssíik-sereg megadható három egész számmal, ezek a Miller-indexek. Tipikus jelölésük h, k és l. Rácssíkok esetén jelenti azokat a rácssíkokat, melyek merőlegesek a h b 1 + k b 2 + ℓ b 3 {\displaystyle h\mathbf {b_{1}} +k\mathbf {b. Crystal Planes and Miller Indices. Crystal planes come from the structures known as crystal lattices. These lattices are three dimensional patterns that consist of symmetrically organized atoms intersecting three sets of parallel planes. These parallel planes are crystal planes and are used to determine the shape and structure of the unit.

Los índices de Miller, en cristalografía, son un juego de tres números que permiten identificar unívocamente un sistema de planos cristalográficos.Los índices de un sistema de planos se indican genéricamente con las letras (h k l).. Los índices de Miller son números enteros, negativos o positivos, y son primos entre sí.El signo negativo de un índice de Miller debe ser colocado sobre.
