Phase 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...
متن کاملDevelopment of force control and timing in a finger-tapping sequence with an attenuated-force tap.
We conducted an experiment to examine age-related differences in the control of force and timing in a finger-tapping sequence with an attenuated-force tap. Participants between 7 and 20 years old tapped on a load cell with feedback on practice trials. They were required to recall the force pattern (300 g, 300 g, 300 g, 100 g) and the intertap interval (400 ms) without feedback on test trials. 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 کاملForce reconstruction from tapping mode force microscopy experiments.
Fast, accurate, and robust nanomechanical measurements are intensely studied in materials science, applied physics, and molecular biology. Amplitude modulation force microscopy (tapping mode) is the most established nanoscale characterization technique of surfaces for air and liquid environments. However, its quantitative capabilities lag behind its high spatial resolution and robustness. We de...
