We investigate the behavior of an oscillating tip operating in tapping mode, e.g. with fixed drive frequency and drive excitation while scanning horizontally an ideal flat surface holding a small corrugation. The numerical simulations are performed to compare the relative vertical and lateral sensitivity of the oscillator when the feedback loop controlling the tip-sample distance keeps constant the...
We have simulated three possible effects of the driving force fluctuation of the cantilever, fluctuation of the surface location and contribution of an additional dissipation due to the sample, with the hope to identify effective methods of improvement of the achievable resolution during a dynamic force microscopy experiment. This study is performed through numerical simulations of the approach-retract...
