AFM is a powerful tool of scanning probe microscopy by recording the interaction of a sharp probe with the sample surface and has been widely used to study the surface characterization of materials in various fields [39,40]. Previously, AFM has been used to achieve surface morphology, ...

The resonant frequency shift(Δf)in the probe oscillation and distance-modulated capacitance(dC/dZ)are simultaneously measured on thin dielectric films as a function of externally applied bias voltage and tip-sample distanceZ. Analysis ofdC/dZspectroscopy has revealed that the probe-tip position ...
These two statements constitute what is known as the laws of sliding friction under dry conditions. Studies of sliding friction have a long history. But there is still no simple model that can be used by an engineer to calculate the frictional force for a given pair of materials in contact....
force-distance curveThe force-distance (F-D) curve in AFM analysis is a useful technique in the field of biophysics and surface science for measuring the physical/chemical properties of a substrate. Herein, the dependence of V z on the F-D curve has been described via a theoretical ...
The equations to calculate normal and lateral force between sample and tip of an atomic force microscopy from the voltage measured were deduced.The method to gain measurement coefficient of an atomic force microscopy on the equation with a force-distance curve was discussed.Different tips and samples...
we will discuss how these new techniques allow for the probing of surface wetting properties in far greater detail. Advances in surface characterization techniques will improve our understanding of surface wetting and facilitate the design of functional surfaces and materials, including for antifogging and...
As the gap distance, dp, between the moving plate and the substrate is much smaller than δ, the damping force is of Couette-flow type and can be expressed as F1=μApdpx˙=c1x˙ where AP is the effective plate area for the damping calculation, including the areas of the plates, finge...

With aforce - distance(F/D) curveit is possible to understand the vertical forces between a probe and a surface. To measure a curve, the probe at the end of a cantilever is pushed into the surface of a sample. Once the probe begins to interact with the sample, the cantilever bends. ...
