Webment of atoms in its unit cell. A simple cubic unit cell is the simplest 3D case. Each of its eight corners contains identical atoms. More-complicated cases can have atoms in the center of the faces or at the center of the cube, known as a face-centered or body-centered cubic unit cell, respectively. They are important structures because many Webdiamond cubic or zincblende lattice can also be face centered cubic. For a simple cubic lattice, it is clear that the nearest neighbor distance is just the lattice parameter, a. …
