Micro X-ray diffraction analysis on a meteorite
In this study a slice of the Northwest-Africa 2086 meteorite was subject to micro X-ray diffraction (XRD) investigations. NWA 2086 was found in 2003 with a total known weight of 780 g.
Two hardened steel samples originating from different steps in the hardening process were analyzed using a specific solution for steel analysis. Sample-1 was taken right after the quenching step, sample-2 additionally underwent an annealing step.
In this application note, the results of the X-ray analysis on the thermal stability of an AlInN/AlN/GaN heterostructure is demonstrated. By using a PIXcel3D detector, reciprocal space maps (RSM) were rapidly measured while annealing the sample at 600˚C. The timeresolved data allowed to monitor the degradation process and its kinetics.
This note describes the possibilities of the PIXcel3D detector for micro-diffraction experiments. This detector offers the flexibility to choose the experimental conditions between maximizing the intensity and optimizing for resolution.
Topographic images reveal irregularities in a non-ideal crystal lattice by means of diffraction contrast. Using the unique 2D performance of the PIXcel3D a setup was realized that allows to collect XRTs of bulk single crystals.
