TLDR
In this article, it was shown that at sufficiently small separations, ∼1−2 A, the tip and flat surfaces in the scanning tunneling microscope or atomic force microscope (AFM) will jump together, irrespective of apparatus construction.Abstract:
It is shown that at sufficiently small separations, ∼1–2 A, the tip and flat surfaces in the scanning tunneling microscope or atomic force microscope (AFM) will jump together, irrespective of apparatus construction. Both continuum and atomistic calculations are presented. We discuss the consequences of the resulting forbidden separations for the behavior of the vacuum barrier as it is quenched, and for the resolution of the AFM.read more

Force measurements with the atomic force microscope: Technique, interpretation and applications
TL;DR: The atomic force microscope (AFM) is not only used to image the topography of solid surfaces at high resolution but also to measure force-versus-distance curves as discussed by the authors, which provide valuable information on local material properties such as elasticity, hardness, Hamaker constant, adhesion and surface charge densities.

Long-range Finnis–Sinclair potentials
Adrian P. Sutton,J. Chen +1 more
TL;DR: Finnis-Sinclair potentials were developed for computer simulations in which van der Waals type interactions between well separated atomic clusters are as important as the description of metallic bonding at short range as mentioned in this paper.

Scratching the Surface: Fundamental Investigations of Tribology with Atomic Force Microscopy.
TL;DR: The goal of this paper is to demonstrate that AFM is capable of producing atomic-scale knowledge, and to focus upon some of the contributions of the AFM to nanotribology.
