Near-Grazing Dynamics in Tapping-Mode Atomic Force Microscopy
In tapping-mode atomic force microscopy, nonlinear e¤ects due to large variations in the force ...eld on the probe tip over very small length scales and the intermittency of contact may induce strong dynamical instabilities. In this paper, a discontinuity-mapping-based analysis is employed to investigate the destabilizing e¤ects of low-velocity contact on a lumped-mass model of an oscillating a...
متن کاملTapping mode atomic force microscopy in liquid
We show that standard silicon nitride cantilevers can be used for tapping mode atomic force microscopy (AFM) in air, provided that the energy of the oscillating cantilever is sufficiently high to overcome the adhesion of the water layer. The same cantilevers are successfully used for tapping mode AFhif in liquid. Acoustic modes in the liquid excite the canti1eve.r. On soft samples, e.g., biolog...
متن کاملFourier transformed atomic force microscopy: tapping mode atomic force microscopy beyond the Hookian approximation
The periodic impact force induced by the tip–sample contact in tapping mode atomic force microscopy (TM-AFM) gives rise to anharmonic oscillations of the sensing cantilever. These anharmonic signals can be understood with a model which goes beyond the common Hookian approximation: the cantilever is described as a multiple degree of freedom system. A theoretical analysis of the anharmonic signal...
متن کاملThe nonlinear dynamics of tapping mode atomic force microscopy with capillary force interactions
We study the nonlinear dynamics of a tapping mode atomic force microscope with tip-surface interactions that include attractive, repulsive, and capillary force contributions using numerical techniques tailored for hybrid or discontinuous dynamical systems that include forward-time simulation with event handling and numerical pseudo-arclength continuation. We find four branches of periodic solut...
متن کاملPhase imaging and stiffness in tapping-mode atomic force microscopy
The dependence of phase angles in tapping-mode atomic force microscopy on the magnitude of tip-sample repulsive interactions was investigated, and phase images of several hard and soft samples were recorded as a function of the free amplitude Ao and the set-point tapping amplitude Asp. The phase angle of probe oscillation increases with decreasing the set-point amplitude ratio Asp/Ao. Phase ima...
