Crystal Lattices

Crystal lattices are structures made up of atoms, ions, or molecules that are arranged in a three-dimensional repeating pattern. These lattices are important in both materials science and physics, as they dictate a crystal's physical properties, such as its hardness, electrical conductivity, and optical properties. For example, a diamond lattice is especially hard and has a high melting point due to its strong covalent bonds. Crystal lattices are also used in optical and electronic applications, most notably for semiconductor devices.
