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. . The intensity changes between isointensity contours by a factor of two. |
