Figure 3.

Close-up views of: (Left) the sphere removal in the square array of Fig. 2b; The area circumscribed by the green curve is where d is the sphere diameter. Right: The same operation but in the hexagonal array of Fig. 2c; here the circumscribed area is . The effect of redeposition changes by switching from a square to a hexagonal array. (Both ion images with HFW = 1.71 μm)
