The 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 کاملExploring the basins of attraction of tapping mode atomic force microscopy with capillary force interactions
We numerically explore the nonlinear dynamics of the oscillating cantilever tip in tapping mode atomic force microscopy. The cantilever dynamics are determined by complex force interactions between the sample surface and the oscillating cantilever tip which are dominated by attractive, adhesive, and repulsive contributions depending on the instantaneous position of the cantilever. We use a mode...
متن کاملCapillary forces in tapping mode atomic force microscopy
We investigated the influence of the relative humidity on amplitude and phase of the cantilever oscillation while operating an atomic force microscope ~AFM! in the tapping mode. If the free oscillation amplitude A0 exceeds a certain critical amplitude Ac , the amplitudeand phase-distance curves show a transition from a regime with a net attractive force between tip and sample to a net repulsive...
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 کاملNear-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...
