Influence of Interdiffusion of Heteromaterials on the Diffraction Focusing of Spherical X-Ray Wave in a Superlattice

详细

The influence of interdiffusion of heteromaterials on the diffraction focusing of spherical X-ray wave in a superlattice is investigated. It is shown that in case of dynamical diffraction of spherical X-ray wave in a short period superlattice, the focal lengths of satellites vary depending on the degree of interdiffusion of heteromaterials of the bilayer. The measurement of focal lengths of satellites allows the determination of structural factors of the superlattice and eventually the calculation of the thickness of transition diffuse layer.
