4-index, or Miller-Bravais, coordinate system Conversion from 3-index to 4-index system = = = w w' t v u-(u +v) (2v' u') 3 1-(2u' v') 3 1 = - [u'v'w'] →[uvtw] Fig. 3.8(a), Callister 7e.-a 3 a 1 a 2 z Multiplying each by 4, we get 1, 4 and 2. Hence (142) are the Miller Indices of the plane. Plane ABC (figure 1.1.5) has intercepts of 2 axial units on X-axis, 2 axial units on Y-axis and 1 axial unit on Z-axis. The reciprocals are ½,1/2 and 1. The LCM is 2. Multiplying each by , we get 1,1,2. 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.

Sadly I haven't been able to come across a single book the gives the derivation of those formulae! 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.

Jun 15, 2003 The Miller Indices are used in crystallography to characterize planes within a the Miller Indices hkl are directly specified by the user via selectors for Miller Index Notation by Roger Nix, Queen Mary University In crystallography, we use Miller indices to specify locations, directions, and In Miller index notation, we will rely on the lattice vectors of the unit cell as our basis. number: travel in the negative a~ 1 direction would be in Jan 11, 2015 As we all know Miller indices of a hexagonal… planes are designated by the 4- index notations (hkil) called as Miller-Bravais (M-B) notation.

in the hcp crystal system there are four principal axes; this leads to four Miller Indices e.g. you may see articles referring to an hcp (0001) surface. Miller Indices for Crystal Structures - YouTube. Watch later.

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.
