Premium Class X-ray Diffraction
Thin Film Analysis
X-Ray Diffraction (XRD) and reflection play a dominant role in the non-destructive characterization of thin layer structured samples. The D8 DISCOVER and DIFFRAC.SUITE software support simple execution of common XRD methods in thin film analysis:
- Grazing Incidence Diffraction (GID) for Surface sensitive Identification of crystalline phases and determination of their structural properties including crystallite size and strain.
- X-ray reflectometry (XRR) for the extraction of thicknesses, material densities and interface structures in multi-layer samples – from simple substrates to highly complex superlattice structures.
- High-resolution X-Ray Diffraction (HRXRD) for the analysis of epitaxial grown sample structures: Layer thickness, Strain, relaxation, mosaicity, composition analysis of mixed crystals.
- Stress and Texture (preferred orientation) analysis
Materials Research
XRD is one of the most important tools in materials research as it allows linking of structural and physical properties of materials. The D8 DISCOVER is the flagship XRD instrument for materials research. Equipped with leading technology components the D8 DISCOVER delivers top performance and full flexibility and enables researchers for a detailed characterization of their materials:
- Phase Identification and structure determination
- Micron strain and crystallite size analysis
- Stress and Texture analysis
- Determination of Particle size and distribution.
- Local XRD analysis using µm sized X-ray beams
- Reciprocal Space Mapping
Screening and Large Area Mapping
The D8 DISCOVER is the ultimate solution when it comes to High-Throughput Screening (HTS) and the mapping of large areas on samples. The UMC sample stages deliver a range of motion that puts the D8 DISCOVER in a class of its own in both motorized translation and weight capacity:
- Hight Throughput Screening (HTS) of well plate and deposited samples in both reflection and transmission
- Mapping of samples with a size of up to 300 mm
- Mounting and mapping samples with weights up to 5 kg
