Author(s) from Durham


The laboratory application of grazing incidence in-plane X-ray diffraction to the measurement of the in-plane (twist) mosaic of GaN epitaxial layers is demonstrated. Only a single measurement containing no extrapolation uncertainty is required. The resolution and intensity are determined for the double axis geometry under different beam conditioning arrangements from a microfocus X-ray tube and a standard sealed source.
