X-ray diffraction facility

Crystals

Our aim is to produce world-class structural analysis on a wide range of materials to improve the understanding of a materials physical and chemical behaviour such as electrical, thermal, magnetic and mechanical properties. By determining the spacing between crystal lattice planes and the length scales over which they persist, we are able to determine the 3D atomic structure of materials.

Specialist technologies

We have several x-ray diffractometers which can be operated in many different modes. All modes reveal different information about the material such as:

  • Residual stress analysis - Determine residual stress within the structure to better understand the physical properties
  • Texture (preferred orientation) analysis - Study preferential ordering and epitaxial growth of crystallites (such as thin films or single crystals)
  • Bragg-Brentano - Phase identification in crystalline and non-crystalline materials as well as quantification of phases within mixtures
  • Line broadening - Determination of crystallite size
  • Hot and cold stage analysis - To study the effect of different temperatures on the structure and crystalline nature of a material
  • Reflectometry – To characterise surfaces, thin films and multilayers
