I - Basic geometrical crystallography (4h)
- Ponctual lattice (lattice, pattern, unit cells, plane, Miller indexes)
- Crystallographic directions and planes (atomic density), reticular distances
- Symmetry operators in the crystal: plane and glide mirrors, rotation and screw axes, inversion center. Two- and three-dimensional space groups, point groups, Laüe groups.
II - Close packed structures and main structural types (3h)
- Description of crystal structures , fcc, hc, bcc
- Interstitial sites
- Covalent structures (diamond), ionic structures (AX, AX2, ABX3, AB2X4 types)
III - Reciprocal lattice (2h)
- Definition, Fondamental properties
- Reciprocal lattice in different crystalline systems
- Interreticular distances versus reciprocal parameters
- Relations in between direct and reciprocal unit cell volumes
IV - X-ray diffraction (3h)
- Nature and production of X-ray, X-ray spectrum, X-ray absorption
- Bragg's law, Conditions of diffraction (Laüe equations, Ewald's sphere)
- Diffracted intensity (atomic diffusion factor, structure factor, anomalous diffusion)
- Classification of experimental methods (powder diagram)
