DMG / DGK Doctoral CourseOrganised by R.E. Dinnebier in cooperation with the Universities of Tübingen and Stuttgart and the Powder Diffraction Working Group of the DGK.
Basics and Application of Rietveld
The aim of the intensive course is to teach the basics of the Rietveld method in theory and practice.
Specifically, the following topics:
• Fundamentals of Powder Diffraction
• Whole Powder Pattern Fitting (WPPF) Fundamental parameters, complex reflection profiles
• Creation of instrument profiles for powder diffractometer
• Correction factors: LP-factor, absorption, microabsorption, extinction, preferred orientation
• Methods for the development of a starting model for the crystal structure
• Application of Penalty Functions, Constraints, Restraints, etc.
• Preparation of Rigid Bodies (flexible polyhedron molecules, such matrices)
• Structure strategies, global optimization methods in direct space, charge flipping
• Use of the difference Fourier method in combination with Rietveld refinements
• Refinement of microstructural parameters using the Rietveld refinement
• Quantitative phase analysis using the Rietveld method
• Comparison of different methods for determining the amorphous portion
• Alternative structural descriptions by symmetry and rotational modes
• parameterization of Rietveld refinements (macro programming)
• Global Optimization stack disordered crystal structures
• Global and local optimization of the pair distribution function
• Creation of Rietveld plots for publications
60 euros for students / PhD students / post-docs (including dinner).
Student DMG members get a subsidy of 50 euros from DMG.
(Course fees for industry participants 400 Euro, if seats are free).
