Solid state physics is the study of how solids behave, in particular, how the presence of other atoms effect properties of other nearby atoms and the applications of these properties. Band theory, an important aspect of solid state physics, explains...

Solid-state physics, the largest branch of condensed matter physics, is the study of rigid matter, or solids. The bulk of solid-state physics theory and research is focused on crystals, largely because the periodicity of atoms in a crystal — its...
