Figure 2
Measured RSMs of the symmetric 004 Bragg reflection for Si0.4Ge0.6/Si samples of thickness 6 nm (a), 29 nm (b) and 200 nm (c). The inclined stripes on the right-hand map are due to diffractometer optics and do not contain information about the investigated sample. [q_{x} = 2\pi q_{x}]. The intensity changes between isointensity contours by a factor of two.  [article HTML]
