Content, Learning Outcome and Preconditions

Content

Many materials in nature and technology are crystalline, i.e. their atomic structure is periodic. For a microscopic understanding of physical properties and as a prerequisite for simulations, detailed knowledge of the atomic structure is essential. The lecture aims at providing fundamentals for structure determination by means of diffraction, i.e. determination of the unit cell as well as type and coordinates of the atoms contained. Since structure determination takes advantage of symmetries, an overview will be given over symmetry operations, the difference between coupling and combination, as well as the classification in point and space groups. Moreover, important methods for the growth of inorganic crystals as well as synthesis of novel organic crystalline materials as Metal-Organic-Frameworks und Covalent-Organic-Frameworks will be introduced. Finally, in relation to nano-materials, we discuss both synthesis and structure determination of two-dimensional materials.

Learning Outcome

The successful participation provides the basic knowledge for structure determination by means of diffraction (Laue equations, Bragg equation, reciprocal space, extinction rules, Ewald construction, strategies for solving the phase problem). One understands the effect of single, combined, and coupled symmetry elements and is able to assign structures to space groups according to their symmetries. An overview about experimental implementations of powder and single crystal x-ray diffraction is provided. The crucial differences between electron vs. x-ray diffraction as well as diffraction on two vs. three dimensional crystals will become clear. Finally, an overview over the most important methods for crystal growth and synthesis of novel crystalline organic materials is obtained.

Module Exam

Description of exams and course work

In an oral exam the learning outcome is tested using comprehension questions and sample problems.

In accordance with §12 (8) APSO the exam can be done as a written test. In this case the time duration is 60 minutes.

Exam Repetition

There is a possibility to take the exam at the end of the semester.

Condensed Matter

When atoms interact things can get interesting. Fundamental research on the underlying properties of materials and nanostructures and exploration of the potential they provide for applications.

Nuclei, Particles, Astrophysics

A journey of discovery to understanding our world at the subatomic scale, from the nuclei inside atoms down to the most elementary building blocks of matter. Are you ready for the adventure?

Biophysics

Biological systems, from proteins to living cells and organisms, obey physical principles. Our research groups in biophysics shape one of Germany's largest scientific clusters in this area.
