|Abstract||Introduction into the fundamental relationships between chemical composition, crystal structure, symmetry and physical properties of solids.|
|Objective||Introduction into the fundamental relationships between chemical composition, crystal structure, symmetry and physical properties of solids. Emphasis: group-theoretical introduction into symmetry, discussion of the factors governing the formation of crystal structures, structural dependence of physical properties, fundamentals of experimental techniques probing the crystal structure.|
|Content||Symmetry and order: lattices, point groups, space groups.|
Crystal chemistry: geometrical, physical and chemical factors governing the formation of crystal structures; close sphere packings; typical basic crystal structures; lattice energy; magnetic crystals; quasicrystals.
Structure/property relationships: Example quartz (piezoelectricity); perowskite and derivative structures (ferroelectrics and high-temperature superconductors); magnetic materials.
Materials characterization: diffraction techniques, optical techniques.
