    • In previous work, an experimental study on grafting of endfunctionalized polymer on textured surface was performed (see Singh, N.; Karim, A.; Bates, F.S.; Tirrell, M.; Furusawa, K. Macromolecules, 1994, 27, 2586-2594). The textured surfaces were created by spin coating colloidal beads of various sizes on a planar substrate and then covering the beads with a layer of aluminium.

    • The monolayer formed on the gold substrate is believed to cause a renormalization of the gold surface and largely alter the surface chemistry but not the nanometer scale topography of the underlying substrate (see Quon, R.A.; Ulman, A.; Vanderlick, T.K. Langmuir, 2000, 16, 3797-3802). Several authors have reported that holes typically one gold atom deep can form during chemisorption of the alkanethiols. However, the origin of these holes remains unresolved. These holes are filled with alkanethiol molecules and do not influence the interfacial properties (see Sondag-Huethorst, J.A.M.; Schönenberger, C.; Fokkink, L.G.J. J. Phys. Chem., 1994, 98, 6826-6834; Dishner, M.H.; Hemminger, J.C.; Feher, F.J. Langmuir, 1997, 13, 2318-2322).

    • An atomic force microscope, where the topographic contrast is caused by force interactions between surface and probe, can also be used for the surface imaging. In our imaging experiments, the resolution of images with atomic force microscopy was generally not as good as that of an STM. In atomic force microscopy, like STM, deformation of the substrate and the monolayer needs to be carefully avoided, expecially as the tip contacts the surface.

    • Roughness analyses depend strongly on tip geometry in scanning probe microscopy. To compare the properties of the two substrates, images were acquired at multiple locations of different samples with use of the same tip. Whereas this was accomplished for the bare gold substrates, it was not possible during STM imaging of monolayers because the tip frequently picked up organic contamination from the surface. The consequent effects on resolution and the necessity for different tips added another experimental constraint for analyzing topography of the monolayer-covered surfaces.
