Abstract
Introduction into the fundamental relationships between chemical composition, crystal structure and physical properties of solids.Emphasis is on the group-theoretical introduction into symmetry, on the discussion of the factors governing the formation of crystal structures and of fundamental crystal structures as well as on the structural dependence of physical properties.
Objective
Understanding of the basic principles of the formation, stability and phase transformations of crystal structures as well as of basic structure/property relationships.
Content
Symmetry and order: Point groups (32 crystal classes), Translation groups (14 Bravais lattices), 2D and 3D space groups. Crystal chemistry: geometrical, physical and chemical factors governing the formation of crystal structures; close sphere packings; typical basic crystal structures; lattice energy; noncrystallographic symmetry - quasicrystals; structure of surfaces. Structure/property relationships: Example super ionic conductors; quartz (piezoelectricity); perowskite and derivative structures (ferroelectrics and high-temperature superconductors); magnetic materials (SmCo5 type). Materials characterization: X-ray diffraction on single and polycrystalline materials.
