Figure 3 displays four 3D images of surface roughness created using different settings in SEMulator3D. (a) (top left) Surface roughness achieved with a mean size setting of 40 nm and count of 1000. Different values were used for mean size and count of the craters that create the surface roughness in Figures (b) Size = 60, Count = 100 (c) Size = 10, Count = 10000 (d) Size = 4, Count = 100000 (Figure 3(b) is shown in the top right, and Figures 3(c) and 3(d) are shown in the bottom left and bottom right)
