Dynamics of vibrating atomic force microscopy [PDF]

Nanotechnology, 2000
An atomic force microscope which is operated in the oscillating mode is an example of an impact oscillator. The description of such dynamical systems can be reduced to a mathematical mapping, which displays a square-root singularity. A direct consequence of this property is the emergence of an infinite series of period-adding bifurcations.

Comment on 'Field ion microscopy characterized tips in noncontact atomic force microscopy: Quantification of long-range force interactions' [PDF]

arXiv, 2013
A recent article by Falter et al. (Phys. Rev. B 87, 115412 (2013)) presents experimental results using field ion microscopy characterized tips in noncontact atomic force microscopy in order to characterize electrostatic and van der Waals long range forces.

True Atomic-Resolution Imaging under Ambient Conditions via Conductive Atomic Force Microscopy [PDF]

arXiv, 2021
Atomic-scale characteristics of surfaces dictate the principles governing numerous scientific phenomena ranging from catalysis to friction. Despite this fact, our ability to visualize and alter surfaces on the atomic scale is severely hampered by the strict conditions under which the related methods are operated to achieve high spatial resolution.

The Stochastic Dynamics of an Array of Atomic Force Microscopes in a Viscous Fluid

, 2006
We consider the stochastic dynamics of an array of two closely spaced atomic force microscope cantilevers in a viscous fluid for use as a possible biomolecule sensor. The cantilevers are not driven externally, as is common in applications of atomic force

Atomic force microscopy in ophthalmic surgery

4th IEEE Conference on Nanotechnology, 2004., 2005
Refractive errors are some of the most common ophthalmic abnormalities. The introduction of excimer laser technology in refractive corneal surgery aims to eliminate all or the major part of the first corneal surface optical aberrations through the modelling of the corneal surface.

Comparison between Atomic Force Microscopy and Force Feedback Microscopy static force curves [PDF]

arXiv, 2013
Atomic Force Microscopy (AFM) conventional static force curves and Force Feedback Microscopy (FFM) force curves acquired with the same cantilever at the solid/air and solid/liquid interfaces are here compared. The capability of the FFM to avoid the jump to contact leads to the complete and direct measurement of the interaction force curve, including ...
