This lecture is intended to diploma and PhD students specialised in the X-ray diffraction. The lecture is an extension of lectures FPL012 (Structure of matter and diffraction of radiation) and FPL030 (Diffraction methods). It covers the following topics: (a) treatment of instrumental phenomena in X-ray diffraction, (b) study of temperature atomic vibrations, (c) study of chemical inhomogeneities and diffusion processes, (d) diffraction on thin films, (e) diffraction on low -dimensionally periodic structures (multilayers, quantum dots) and (e) some computational methods in structure analysis. The complete course on advanced methods in X-ray diffraction consists of two lectures: FPL029 (X-ray diffraction study of the real structure of matter) and FPL040.

1. Accuracy in diffraction experiment - instrumental aberrations, microstructural parameters, geometrical factors, sample transparency, absorption of x-rays, surface roughness, primary and secondary extinction, preferred orientation of crystallites

2. Dynamical effects in crystals.Thermal vibrations, diffusion, chemical inhomogeneity

3. Short and long range ordering - diffractional study of local arrangement at phase transition, x-ray diffraction on structures with large periodicity (multilayers, superconductors) high and low angle diffraction, reflectivity (optical theory, DBWA)

4. Experimental methods of determining the short range orderining - EXAFS, diffuse scattering

5. Computional methods in applied structural analysis - simulating of diffraction pattern (Lazy Pulverix), refinement of real crystal structure (the Rietveld method), deconvolution. Determinination of thin film, multilayer and superconductor structure parameters (SUPREX)
