Localised Tuneable Composition Single Crystal Silicon-Germanium-on-Insulator for Low Cost Devices

Figure 11

Comparison of SiGe composition profiles of the central strip of a tailored tree-like structure and a straight strip. (a) Graph and (b) schematic. The final set of branches have been omitted from the central strip of the tailored tree-like structure to display only the uniform composition region. The straight strip data has been normalised from Figure 4 to match the length of the tailored tree-like structure. The complete mixing model has been fitted to the straight strip data [33]. A linear fit has been added to the tailored tree-like structure data.
