Bravais lattice

Bravais lattice Definition

It is a distinct lattice that normally repeats in order to fill the whole space. In mathematics, a lattice is a regular, geometric arrangement of points, particles, or objects throughout an area or a space, especially the arrangement of ions or molecules in a crystalline solid. A Bravais lattice is generally any of the 14 possible three-dimensional configurations of points that describe the orderly arrangement of atoms in a crystal. It can be generated by three unit vectors, a1, a2 and a3 and a set of integers that are denoted as n1, n2 and n3. In this way, each lattice point is identified by a vector R to obtain: Continue reading
