Maciej Zubko, PhD, Assoc. Prof.
Classical crystallography is based on the description of the crystal structure by determining the position of atoms in a unit cell and is the essential tool for materials characterization. Developed for over a hundred years, it crystallography has established methods allowing to determine the crystal structure of the studied substances on the basis of X-ray or electron diffraction. It turns out, however, that for some types of materials such a description is insufficient because they exhibit a disordered crystal structure. In such cases, classical crystallography provides only information of the materials’ average crystal structure. Therefore, the information obtained on this basis may not be sufficient to fully know and understand the properties of the studied materials. The lecture will present selected methods of analyzing the structure of disordered materials on the basis of X-ray and electron diffuse scattering.
