Crystallographic zone
The translational invariance of a crystal lattice is described by a set of unit cell, direct lattice basis vectors (contravariant or polar) called a, b, and c, or equivalently by the lattice parameters, i.e. the magnitudes of the vectors, called a, b and c, and the angles between them, called α (between b and c), β (between c and a), and γ (between a and b). Direct lattice vectors have components measured in distance units, like meters (m) or angstroms (Å). WebThe Brillouin-zone database offers k-vector tables and figures which form the background of a classification of the irreducible representations of all 230 space groups.. The space groups are specified by their sequential number as given in the International Tables for Crystallography, Vol. A.You can give this number, if you know it, or you can choose it …

WebDirections, Planes and Zone Axes. Here we introduce the concepts relating to the labelling and representation of crystallographic planes and directions. This is usually done using the Miller or Miller-Bravais notations, which are described below. Crystallographers often explicitly state the type of beam used, as in the terms X-ray crystallography, neutron diffraction and electron diffraction. These three types of radiation interact with the specimen in different ways. X-rays interact with the spatial distribution of electrons in the sample.
