CHEM8039 Materials Characterization by X-Ray Diffraction

Module Overview

This module is aimed at chemists, physicists and engineers who wish to investigate the structural characteristics of materials via X-ray diffraction. It will begin by covering the basics of powder diffraction theory and rudimentary data interpretation and then move on to discuss more advanced techniques and their application to thin films and engineered materials.

Learning Outcomes

Having successfully completed this module you will be able to:

  • Students will become familiar with the types of information that x-ray diffraction can provide on the structure of a wide variety of samples.
  • They will learn to interpret real data and extract structural information.
  • Through the coursework they will gain a greater insight into their own characterisation problems.
  • Extensive experience of the software packages PDXL, GSAS & Rex.Cell will be gained.
