Abstract
AbstractA simulation program based on the Takagi–Taupin equations from the dynamical theory of X-ray diffraction has been developed. The novelty of the program lies mainly in that it includes the elastic distortion of coherent epitaxial layers by employing a model based on the elasticity theory of materials. The simulation model is fairly flexible, allowing the calculation of any symmetric or asymmetric reflection, any substrate orientation, graded and relaxed layers, and instrumental effects. Some simulation results for different materials and multilayered structures are presented. A preliminary study of the influence of beam dispersion and detection noise has also been carried out.MST/3251
