D8 DISCOVER Applications

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
