Each coordinate is thus 0 or a proper fraction, except that in NaCl-type crystals the unit-cell dimension is often taken as 2. Symbols based on Miller Indices WebThe position in 3D space of each crystal face is plotted on a stereographic net such as a Wulff net or Lambert net. The pole to each face is plotted on the net. Each point is labelled with its Miller index. The final plot allows the symmetry of the crystal to be established.

Mechanical characterisation of novel aperiodic lattice structures

WebIn a crystal, there exist directions and planes which contain a large concentration of atoms. Therefore, it is necessary to locate these direction and planes for crystal analysis and to use some conventions to specify them in a crystal. A crystallographic direction is defined as a line between two points or a vector. WebA crystal family is determined by lattices and point groups. It is formed by combining crystal systems that have space groups assigned to a common lattice system. In three dimensions, the hexagonal and trigonal crystal …
