Crystal structure: introduction to lattice properties.
Lattice and crystals. A lattice is a three-dimensional periodic array of identical building blocks. The building blocks are atoms or groups of atoms. The crystals usually come with imperfection of structure and impurities. The periodicity of crystals is well established by the experimental studies of X-ray, neutron and electron diffraction patterns. A solid is a…
