| Outline of Final Research Achievements |
We perform AFM simulation involving different scale phenomena ranging from macroscopic to atomic scale using a new kind of computational method developed by our research group. The dissipation of the mechanical energy of the cantilever oscillation of the AFM has been observed, however, its mechanism has not yet clearly understood. We successfully show the microscopic mechanism of the dissipation which is attributed to the hysteresis and nonconservative properties of the interatomic force that acts between the atoms in the tip and sample surface.
