A study of the growth sector boundary between the -XandZsectors in synthetic quartz II. Fringe contrast

X-ray Topographic Characterization of L-Arginine Phosphate Monohydrate Crystals

“…The contrast of the grown-in defects such as, dislocations and growth sector boundaries can be seen clearly in them, and from which, a map of growth defects within the crystal was obtained. Such bands are so-called "X-ray dynamical fringes" similar to the case of stacking faults [PARPIA 1978, LIU et al 1996. The slice #0020c-2 (Fig.…”

Theoretical and experimental study of growth sector boundaries in deuterated potassium dihydrogen phosphate single crystals

“…If the function F(x) is odd (no necessary condition) and has the Fourier transformation 00 The four functions 14(v, y) are listed up in the Appendix. The integral terms in equations ( 5 ) to (8) express the effect of surface relaxation. In the case without relaxation they equal zero.…”

“…They may be successfully used for qualitative interpretation of X-ray contrast, despite of the fact that they contain some serious simplifications. These are, e.g., a constant net rotation within a thin relaxation region and no rotation outside of it [l]; a constant curvature of the planes parallel to the boundary and the divergence of the stresses at the boundary outcrops [8].…”
