Description

Master's Programme in Materials Research is responsible for the course.

Module where the course belongs to:

  • MATR300 Advanced Studies in Materials Research
    Compulsory for:
    1. Study Track in Inorganic Materials Chemistry (if student chooses Inorganic materials chemistry course package III -course package)

    Optional for:

    1. Study Track in Experimental Materials Physics

The course is available to students from other degree programmes.

Basics: physics, mathematics, chemistry.

Courses on other material characterization methods supplement this course. They can be taken either before, parallel or after this course.

Understanding the fundamental concepts of X-ray crystallography.

Understanding of the undertaking a single crystal x-ray structure determination themselves (crystal selection and mounting, data collection, data processing, structure solution, structure refinement, evaluation of the final crystal structure).

Become competent to interpret crystallographic results.

Able to apply this knowledge to problems in own research and literature.

Can be taken the early or late stages of the studies (see Prerequisites).

Given every year in the spring term (Period III).

Minimum number of participating students 9, otherwise postponed to the next study year.

Basics: Basic Definitions, Unit Cell, Crystal Systems, Bravais Lattices.

X-Rays: Generation of X-Rays, Interaction of X-Ray with Matter.

X-Ray Diffraction: The Geometry of X-Ray Diffraction, Reciprocal Lattice and Ewald Construction, Structure Factors.

Crystal Symmetry and Space Groups: Simple Symmetry Elements, Crystal Classes, Symmetry Elements Involving Translation, Space Groups, Symmetry of the Reflection Pattern – Laue Groups, Space Group Determination.

Experimental Methods: Growth, Choice and Mounting of a Single Crystal, Measuring the Diffraction Pattern of Single Crystals, Data Reduction.

Structure Solution: Fourier Transforms, Patterson Methods, Direct Methods.

Structure Refinement: L.S. Methods, Figures of Merit, Refinement Techniques.

Additional Topics: Extinction, Anomalous Dispersion and ‘Absolute Structure’, Disorder, Error and Pitfalls, Interpretation and Representation of Results, Crystallographic Databases.
