STRUCTURE DETERMINATION OF QUASICRYSTALS
Résumé
The structure determination of quasicrystals remains a complex and challenging problem. The most fruitful approach to this problem so far, has been by the use of the high dimensional crystallography. In this paper we introduce the basic tools used in this approach and illustrate it with the case of the CdYb icosahedral phase determination. The relation between the high dimensional description and the resulting 3D structure is presented. We briefly introduce the concept of phason modes and its consequences on the diffraction pattern.
