This course is aimed to introduce any phenomena occured in solid state. This will be started with an introduction to bonding types in solid state such as covalent bond, hydrogen, van der Waals and ionic. Later on, discussions will be continued on ctystal structures, symmetrical points, crystal classifications and smple structures and also refraction of periodic structures. Dynamic properties of crystal and properties of heat in crystal will also be given. Principles of free electron, band structure in solid state, electron motion in magnetism and mobility phenomenon describe a real explanation in solid state followed by superconductors. Dielectric properties in solid state, semiconductor solid state and superconductor will also be discussed.
