WebGrazing-angle X-ray diffraction Definition: A method for determining structure by directing a beam of X-rays at the sample and detecting the positions and intensities of the diffracted X-rays as a pattern of spots on a photographic plate.The incident X-ray beam strikes the sample at a small angle (<5 deg.) close to the critical angle of total external X-ray reflection. WebGrazing Incidence X-ray Diffraction (GIXRD) is a surface sensitive diffraction technique that utilises a small incident angle X-ray beam to limit penetration into the bulk material as well as optimise the intensity. This makes it a powerful tool for: Determining phases present at the sample surface and in multi-layer thin films or passivation ...
