A few years after the invention of the scanning tunneling microscope (STM), the atomic force
microscope (AFM) was developed. 1 Instead of measuring tunneling current, a new physical …

In this review, we present various results obtained by friction force microscopy in the last
decade. Starting with material-specific contrast, commonly observed in friction force maps …

Sliding friction between the tip of a friction force microscope and NaCl (100) was studied to
deduce the velocity dependence of friction forces on the atomic scale. A logarithmic …

Direct and simultaneous measurements of the normal and lateral forces encountered by a
nanosize spherical silicon tip approaching a solid surface in purified water are reported. For …

The friction force on a nanometer-sized tip sliding on a surface is related to the thermally
activated hopping of the contact atoms on an effective atomic interaction potential. A general …

The velocity and humidity dependence of nanoscopic sliding friction has been studied on
CrN and diamondlike carbon surfaces with an atomic force microscope. The surface …

We have used an ultrahigh vacuum atomic-force microscope to study the variation in contact
radius and friction with applied force between a silicon tip and a NbSe 2 sample. The data …

The analysis of lateral force microscopy experiments is discussed with emphasis on
calibration issues and the statistical treatment of the original data in order to obtain reliable …

The sliding of a sharp nanotip on graphene completely immersed in water is investigated by
molecular dynamics (MD) and atomic force microscopy. MD simulations predict that the …

In atomic force and frictional force microscopy, quantitative interpretation of lateral stiffness
at the tip-sample contact requires a detailed understanding of all factors contributing to the …
