Voto Finale

The main goal of the course is presenting methodological and structural aspects for the characterization of ionic and molecular solids, mostly, but not only, of inorganic nature.

-Chistal Chemistry
- Structural defects in crystals and nanocrystals
- Main properties of solid state materials

- Crystal Chemistry: close packing of spheres; interstitial cavities; hcp, fcc and bcc solids; polytypism of crystal structures; coordination polyhedra; reference inorganic structure (halite, sphalerite, fluorite-antifluorite, diamond, wurtzite, CsCl, AX2 and A2X compounds); oxides with AmBnOp structure (perovskites and spinels); silica and silicates classification.
- Structural defects, non-stoichiometric solids and solid solutions: intrinsic points defects (Schottky, Frenkel), extrinsic point defects, color centers; non-stoichiometric compounds; solid solutions; Vegard Law and other methods for the characterization of the solid solutions. Exended defects: shear planes, intergrowths, stacking faults, antiphase domains, dislocations.
- Electronic, magnetic and optical properties of solid materials.
- Polymorphism: concept development and nomenclature; technological relevance; structural origin; thermodynamic description of monotropic and enantiotropic polymorphs; examples.
