Synopsis:

Description of fundamental properties of solids following the regular long distance ordering of atoms in a crystal lattice. Based on interaction between atoms in solids various types of crystals and their properties are defined. Lattice dynamics of simple lattices in harmonic approximation and thermal properties of crystals are studied. Periodic potential of crystal lattice allows description of energy structure via electronic energy bands. The goal is to present a wide phenomenological base of physical properties of crystalline solids.
