Symmetry & Crystal Structures

Symmetry & Crystal Structures. Solid State Physics 355 Topic 1. Crystals. Atoms that are bound together, do so in a way that minimizes their energy. This most often leads to a periodic arrangement of the atoms in space. If the arrangement is purely periodic we say that it is crystalline.
