PeakForce Tapping sequence highlighting unique lattice defects, as well as adsorbates. In this sequence you can also see 2 different adatoms appear on the surface and then disappear in subsequent frames.

Another great advantage of PeakForce Tapping, particularly when imaging at the atomic scale, is you can obtain a forces curve for any pixel in the image. Here are two examples of force distance curves collected during Peak Force Tapping imaging. One set of approach / retract curves was collected on calcite...

The cycle averaging of Tapping limits performance because 1) the high resolution tip-sample interaction only occurs when the tip is close to the sample, and this is a fraction of the cycle, and 2) at low imaging forces, the effects of long range forces dominate the cycle. (This is also why atomic Tapping...

Image of the cleavage plane of calcite taken with the Dimension FastScan using a standard cantilever (SNL+, 60um) in water. In the image you can see two crystal planes (brown and blue) separated by the dissolving crystal front (red). We have overlaid the atomic model of the oxygen atoms in the calcite...

When compared to other common microscopy techniques (optical, SEM, TEM), the atomic force microscope’s (AFM’s) broad potential for nanoscale imaging and characterization of numerous physical surface properties has been somewhat offset by its slow imaging speed. Thus, the AFM has sometimes...

This experiment shows 275, 5um, 1024x1024 pixel image, taken at 17Hz (170um/s tip velocity). Each image is analyzed using the blind reconstruction method in the NanoScope SW to determine the estimated tip diameter, and is plotted versus image number. The results show that over this entire 270 image sequence...
