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. See more Crystallography is the experimental science of determining the arrangement of atoms in crystalline solids. Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics See more • Coordinates in square brackets such as [100] denote a direction vector (in real space). • Coordinates in angle brackets or chevrons such as <100> denote a family of directions which … See more Crystallography is used by materials scientists to characterize different materials. In single crystals, the effects of the crystalline arrangement of atoms is often easy to see macroscopically because the natural shapes of crystals reflect the atomic … See more A number of women were pioneers in X-ray crystallography at a time when they were excluded from most other branches of physical science.
