Gt. Baumbach et M. Gailhanou, X-RAY-DIFFRACTION FROM EPITAXIAL MULTILAYERED SURFACE GRATINGS, Journal of physics. D, Applied physics, 28(11), 1995, pp. 2321-2327
X-ray diffraction from simple monocrystalline and epitaxial multilayer
ed surface gratings will be described theoretically by use of a distor
ted wave Born approximation of second order. The intensity patterns of
simple and multilayered gratings have been simulated by this treatmen
t and compared with the kinematical approximation. The gratings act si
multaneously as reflection and transmission gratings. This gives rise
to Umweganregung also between the grating and the dynamical diffractin
g planar structure including the substrate.
