X-RAY REFLECTIVITY (XRR)

Characterize the physical surface properties of your thin films, multilayer coatings, and interfaces.

Determine:

  • layer thickness
  • surface and interface roughness
  • density
  • chemical composition
ROCKING CURVES

High-resolution rocking curves can be used to analyze epitaxial single-crystal films and determine the crystalline perfection of bulk single crystals.

Determine:

  • layer composition and thickness
  • mismatch, relaxation (lattice strain)
  • layer tilt, curvature, and misorientation
  • mosaicity
  • dislocation density
RECIPROCAL SPACE MAPPING

This high-resolution technique provides the most information about epitaxial thin films and is necessary to analyze strained films.
