X-ray diffraction is the main method for structural analysis of materials and for the study of their structural quality, due to the unsurpassed precision in the measurement of the crystalline lattice parameters. The X-Ray Diffraction Laboratory is equipped with modern equipment which allows for advanced X-ray diffraction characterization of very different crystalline materials systems.
The Rikagu SmartLab 9 kW high-resolution diffraction system represents the state of the art in fully automated modular XRD systems. The system incorporates a high-resolution theta/theta closed loop goniometer drive system, CBO, an in-plane scattering arm, a 9.0 kW rotating anode generator, and a fully automated optical system to make advanced measurements possible for both expert and novice users of the system. Both Parallel beam and Bragg-Brentano modes can be operated.
This diffractometer allows for the investigation of preferred orientation, residual stress analysis of powders, polycrystalline materials, and polycrystalline thin films as well as single crystalline films. With this system it is also possible to perform rocking curve measurements in the sample-detector decoupled mode and to take diffraction profiles in grazing incidence. In addition, it is equipped with a capillary module for small amounts of powdered samples and a hot stage operated in various inert environments (up to 1100°C). Another available mode is X-ray reflectivity, which provides information on the thin film thicknesses, densities and surface roughness.
Types of samples that can be measured:
- Thin films
- Bulk samples
- Powder diffraction
- Thin film analysis
- Rocking curve – crystal quality
- Pole figure – 3D texture analysis
- In-situ heating up to 1100°C, including powders
- Reflectivity measurements (XRR) of thin films for measuring thickness, roughness and density
- Transmission mode (capillaries)
- Residual stresses measurement
- Grazing angle – depth profile
- Small area measurement 0.4mm, automated lateral scan mode
