We also propose a simple model to simulate the force titration process. The force between the tip and sample can be estimated according to the slope coef®cient of the curve of energy versus distance. This curve can lead to a better understanding of the force titration curves of amino-group-terminated SAMs.||URI:||https://hdl.handle.net/10356/95785
