متن کاملSingle atomic contact adhesion and dissipation in dynamic force microscopy.
By combining dynamic force microscopy experiments and first-principles calculations, we have studied the adhesion associated with a single atomic contact between a nanoasperity--the tip apex--and a semiconductor surface--the Ge(111)-c(2 x 8). The nanoasperity's termination has been atomically characterized by extensive comparisons of the measured short-range force at specific sites with the che...
متن کاملSolitonic mechanisms of dissipation in adsorbed atomic mono-layers
In this work we investigate the possibility of a dissipation topography sensitive to local bonding defects (solitons or kinks) of adatoms monolayers. We carry out this study in a very idealized scheme: the standard Frenkel-Kontorova model, with a harmonic chain representing the layer of atoms adsorbed on a crystalline surface, interacting with a periodic potential representing the solid substra...
متن کاملForce-gradient-induced mechanical dissipation of quartz tuning fork force sensors used in atomic force microscopy.
We have studied the dynamics of quartz tuning fork resonators used in atomic force microscopy taking into account the mechanical energy dissipation through the attachment of the tuning fork base. We find that the tuning fork resonator quality factor changes even in the case of a purely elastic sensor-sample interaction. This is due to the effective mechanical imbalance of the tuning fork prongs...
متن کاملEnergy dissipation in multifrequency atomic force microscopy
The instantaneous displacement, velocity and acceleration of a cantilever tip impacting onto a graphite surface are reconstructed. The total dissipated energy and the dissipated energy per cycle of each excited flexural mode during the tip interaction is retrieved. The tip dynamics evolution is studied by wavelet analysis techniques that have general relevance for multi-mode atomic force micros...
