Abstract :
Translation Moiré pictures were first observed in interference topographs obtained using Synchrotron radiation. A film interferometer was prepared on the base of the GeSi heterosystem. Another film interferometer, which presents the heterosystem of epitaxial Si/ porous Si/ substrate Si, permitted us to observe a decrease in the bending of the film atomic planes at annealing of the heterosystem. This bend smoothing was calculated with the sensitivity better than 1 إ with the use of X-ray interference topographs. Contrast peculiarities in Moiré pictures are discussed for nondiffracting layers and crystal quantum wells.
