Solid state physics lectures contain information about materials bond and atom vibrations and their influence on specific heat capacity, heat transport and thermal dilatation. On the base of this knowledge the dielectric materials as ferroelectrics, polymers and liquid crystals are studied. The physical picture of these materials is completed by dielectric phenomena and polarization effects. Special attention is devoted to semiconductors and contact phenomena as well as optical properties of materials. Further the magnetic and superconducting materials are described on the base of quantum mechanics.
