Furthermore, a correction factor of √4/3 is required in the most common case of a rectangular beam cantilever. Butt, H.-J., Jaschke, M. Nanotechnology, 1995, 6, 1.

    • In practise it is difficult to compare different tips with each other, because they exhibit different tip-radii, which results in different contact areas and thus in a different number of interacting molecules contributing to the total adhesion force. It seems that the tip radii do not differ significantly in our measurements, since the adhesion forces of all five different tips on the 10/10 substrate are (almost) the same, whereas the adhesion forces of the 10/10 tip on the other substrates seem independent of the chain length (Figure 2). The adhesion force on the 10/10 substrate can be regarded as an internal reference for the adhesion measurements performed with the different tips.

    • 21 Generally, one would expect non-Amonton's-law-like friction-load behavior in single asperity friction force measurements. The reason for the fact that Amonton's-law-like friction is often found in SFM measurements is believed to be the nanometer scale roughness of the tip, making it behave like a multi-asperity contact.
