Non-coplanar GID is used for determining information in the plane of the sample surface, which is why it is also referred to as “in-plane” diffraction. In particular, lattice parameters, surface-plane relaxation, texture and crystallite size are among the sample information that can be obtained with GID.
Soft matter such as gels, polymers and liquids, single crystals, polycrystalline sheets and powders can be investigated. Particular applications include:
- Polycrystalline materials: Phase ID and lattice parameters, lateral grain size, in-plane preferred orientation
- Single crystals: in-plane lattice parameter (high accuracy using the bond method), azimuthal orientation of layers with respect to the substrate, evidence of twinning
- Soft matter: in-plane size and shape of colloids, distance correlation functions, length scales of in-plane density modulations
- Any other in-plane applications where standard diffraction geometries fail due to lack of scattered intensity
