FIG. 1.

Integrated Bragg and diffuse intensities vs coverage for the Bragg peak. Solid lines are guides to the eye. The dashed curve is calculated for and demonstrates the presence of disorder from misfit strain at high coverage. The inset shows transverse scans across the Bragg peak for selected coverages.

FIG. 3.

X-ray reflectivity for of deposited on at . Solid line is the best fit for predominately eight-layer islands grown on top of the substrate with a wetting layer roughness of . Dash-dotted line is the same fit with a smoother wetting layer, . Dashed line is a fit with the islands grown on-top of a wetting layer with . Inset shows fits to a portion of the reflectivity near the peak for seven-layer islands (dashed-dot line), eight-layer (solid line), and ning-layer (dashed line) islands.
