Figure 4.6.3.3
Schematic diffraction patterns for 3D IMSs with (a) 1D harmonic and (b) rectangular density modulation. The modulation direction is parallel to . In (a) only first-order satellites exist; in (b), all odd-order satellites can be present. In (c), the diffraction pattern of a harmonic displacive modulation along with amplitudes parallel to is depicted. Several reflections are indexed. The areas of the circles are proportional to the reflection intensities. |
