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 and the other was collected on mica. The mica

An atomic resolution image of Calcite, this time taken on he Dimension Icon (90um scanner, large sample platform, SNL+ probe) showing the height and stiffness channels. (In the software, this is called Modulus, however, at the atom level, modulus is not defined since it is a continuum property. Here we simply note that areas where the force curve slope

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 on the lower plane, and there you can see the zig
