Figure 5

Images of the same Platinum film as shown in Figure 3. The images shown were acquired at the same value of the feedback loop, but at different imaging speeds (from left to right: 0.5, 1, 2, 4, and 8 lines/s). As previously the upper row shows topographic images, the middle row amplitude images and the lower row graphs of the corresponding PSD curves of surface roughness. Again, lateral size of the larger images is 10 μ m, smaller images show a zoom of 1 μ m. The total grey scale of all images is 5 nm. The grid lines for the PSD graphs are Δlog[κ] = 1 (horizontal axis) and Δlog[PSD] = 1 (vertical axis).
