Information

Aims, contents and method of the course

The course intends to provide a general introduction into the tasks of crystal structure determination (a) from X-ray powder data as well as (b) from X-ray single crystal data.
These techniques will be demonstrated on selected examples.
The course is highly recommended as a specific preparation for master work and/or a doctoral thesis in materials chemistry.

Contents (part in Physical Chemistry): Introduction to production and properties of X-rays. Fundamental principles of X-ray diffraction. Indexation of X-ray powder patterns (Example 1). Techniques and interpretation of powder diffraction data; qualitative and quantitative analysis of crystalline powders (Rietveld analysis) as well as ab-initio determination of an unknown crystal structure from X-ray powder data (Example 2). Methods of solving the phase problem. Direct methods for structure determination and refinement from X-ray single crystal data (Example 3). Introduction to EPMA (Electron Microprobe Analysis; Example 4).
The introductory course is accompanied by tutored exercises on these major tasks (1-4) and by concomitant training in various computer programs (Fullprof, Oscail, Atoms).

Assessment and permitted materials

The judging of students is derived from the activity in seminars, the engagement during the experiments, and from the result of final questioning.

Minimum requirements and assessment criteria

Correct handling of modern research facilities, good physico/chemical understanding, suitable documentation of experiments, and the specific preparation for master work and/or a doctoral thesis in materials chemistry.

Examination topics

The lab course uses modern audio-visual tools and state-of-the-art research instruments.
