14. See EPAPS Document No. E-APPLAB-87-013542 for a comparison of the motion of a cantilever with (a) Q∼2 (fluid tapping) and (b) Q∼50 (operation in air) with the same free amplitude and set-point. The top panels show how the cantilever base and cantilever move with respect to the surface. Notice how much more the base needs to move with low- Q system compared to the high- Q system. The middle panels show the deflection trajectories over one cycle, with the low- Q system displaying the enhanced anharmonicity characteristic of fluid tapping AFM. The bottom panels show the time resolved tip/sample force interactions.
