| Abstract: | The phase image in tapping mode of atomic force microscope indicates that the process of interaction and separation between the tip and the samples dissipates energy, which is primarily due to the liquid bridge in ambient air. This paper studies the dynamic process of the formation and rupture of liquid bridge in tapping mode of atomic force microscope in order to reveal the AFM working mechanism, and finally the dissipation energy in tapping mode of AFM is determined. |
