Day 2: The structure of matter – 3D materials analysis
Kurs für Schülergruppen

New functional materials are essential for technological improvements. Their specific properties arise from the materials structure on the micro and nanoscale, created artificially or utilizing self-organization. Thus, a fundamental understanding of materials properties requires knowledge of their structure down to the atomic scale.

Experimente

  • overview on different methods for 3D materials characterization
  • physics of diffraction techniques
  • remotely control an X-ray diffractometer to analyze the crystal structure of a material

The materials classes addressed in this course are semiconductors and metals. Characterization techniques cover 3D (tomographic) imaging and diffraction. Particularly, X-ray diffraction in Bragg-Brentano geometry for single crystalline and polycrystalline materials is introduced. The participants measure crystallographic data of single crystalline materials using remotely controlled X-ray diffractometers. A brief introduction to Miller indices allows a quantitative evaluation of the measurements.

Participants should be familiar with fundamentals of diffraction and interference. X-ray diffraction and crystallography will be introduced in the course / webinar.
