ABSTRACT
Diffraction imaging using x-ray topography (XRT) and x-ray multiple diffraction (XRMD) provide valuable tools for examining the growth defects in crystals and the distributions from ideal lattice symmetry (microcrystallography). The topographic x-ray multiple diffraction microprobe (TMDM) combines the complementary aspects of both techniques enabling XRT and XRMD studies within the same instrument providing a useful resource for the structural characterization of materials that are not very stable in vacuum and electron beam environments. The design of the TMDM instrument is described together with data taken on GaAs (001) and potassium dihydrogen phosphate (001).

    It is shown that the atomic displacements (induced by foreign layers) comparable with or smaller than the interatomic distances can be detected in perfect multilayer systems by double-crystal X-ray diffractometry alone. It was earlier thought that the detection of displacements as small as those...
