Figure 9
Symmetric (004) RSMs of the MQWs on SiGe microcrystals recorded at different azimuthal directions φ of the incidence plane for (a) φ = 0°, (b) φ = 30° and (c) φ = 44°. (d) The SiGe microcrystals with the SiGe/Si MQW structure are terminated by (113) facets which are responsible for the truncation rods along the [113] directions. (e) A perspective view of the 3D symmetric (004) RSM reconstructed using the Radon transform from QxQz maps recorded under different azimuths. It demonstrates the directions of truncation rods perpendicular to the crystal facets. The red arrows indicate the projection views of the maps in panels (a), (b) and (c).
