Unit Cell
... A crystal is an array of atoms packed together in a regular pattern. A unit cell of a pattern is a piece of the pattern which, when repeated through space without rotation and without gaps or overlaps, reconstructs the pattern to infinity. For filling space without holes, a unit cell must be either ...
