Abstract
Changes in moiré fringe patterns due to dynamical electron diffraction effects have been observed in electron micrographs of epitaxial deposits of silver on molybdenite. These changes occur in regions of the specimen where the film is curved, i.e. in the vicinity of bend contours. The most easily detected change due to diffraction effects is a deviation of the moiré fringes as they obliquely cross a Bragg fringe. The measurable parameters of these deviated regions are in good quantitative agreement with theoretical predictions based on the column approximation for the two-beam case.
