Crystallography

Epitaxy refers to the deposition of a crystalline overlayer on a crystalline substrate.

In mathematics, physics and chemistry, a space group is the symmetry group of a configuration in space, usually in three dimensions.

A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions or molecules in a crystalline material.

Crystallography is the experimental science of determining the arrangement of atoms in the crystalline solids (see crystal structure).

A quasiperiodic crystal, or quasicrystal, is a structure that is ordered but not periodic.

A single crystal or monocrystalline solid is a material in which the crystal lattice of the entire sample is continuous and unbroken to the edges of the sample, with no grain boundaries.

In geometry, the stereographic projection is a particular mapping (function) that projects a sphere onto a plane.

Powder diffraction is a scientific technique using X-ray, neutron, or electron diffraction on powder or microcrystalline samples for structural characterization of materials.

Crystallization is the (natural or artificial) process where a solid forms where the atoms or molecules are highly organized in a structure known as a crystal.

In geometry, a point group is a group of geometric symmetries (isometries) that keep at least one point fixed.

X-ray crystallography is a tool used for identifying the atomic and molecular structure of a crystal, in which the crystalline atoms cause a beam of incident X-rays to diffract into many specific directions.

The Scherrer equation, in X-ray diffraction and crystallography, is a formula that relates the size of sub-micrometre particles, or crystallites, in a solid to the broadening of a peak in a diffraction pattern.

The Cauchy–Born rule or Cauchy-Born approximation is a basic hypothesis used in the mathematical formulation of solid mechanics which relates the movement of atoms in a crystal to the overall deformation of the bulk solid.

Diffraction topography (short: "topography") is an quantum beam imaging technique based on Bragg diffraction.

A crystal is a solid material whose constituent atoms, molecules, or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions.

Friedel's salt is an anion exchanger mineral belonging to the family of the layered double hydroxides (LDHs).

Neutron scattering, the scattering of free neutrons by matter, can refer to either the physical process or the experimental technique which uses this process for the investigation of materials.
