The 6th Workshop on Structural Analysis of Incommensurate Crystals continues a series of workshops on the structure determination of incommensurate crystals at the University of Bayreuth. Purpose is to present an overview of the methods of structure determination and structural analysis of incommensurately modulated structures and composite crystals. Lectures will cover the basic principles of the superspace description of modulated structures as well as advanced topics, like the method of Charge Flipping and the Maximum Entropy Method in superspace. In addition to the series of lectures the participants will have the opportunity to practice structure refinements using the computer program JANA2006 (written by V. Petricek, M. Dusek and L. Palatinus, Prag). A step-by-step tutorial with several examples will be provided, but your own data sets are welcome, too.

Invited speakers

  • V. Petricek, Prague 
  • L. Palatinus, Lausanne
  • M. Dusek, Prague
  • N. Bolotina, Moscow
  • A. Schönleber, Bayreuth
  • S. van Smaalen, Bayreuth 

A selection of topics

  • Superspace description of incommensurate crystals
  • Superspace symmetry
  • Fourier methods
  • Maximum Entropy Method in superspace
  • Charge Flipping and determination of incommensurate structures
  • Crystal chemistry of aperiodic structures

Computer course

In the afternoon sessions the participants will have the opportunity to practice structure refinement and structure determination with the computer program JANA2006. A script will be provided that will guide you step-by-step through the procedure of structure analysis for a series of worked-out examples. Alternatively, you can bring your own data.
