| Abstract: | A research method on nano--contact is in-troduced in this paper. The mechanics model between thetip of AFM and sample surface, which includes the repul-sive force, is set up by continuance medium, followed bysimulation of the mechanics model. The simulation re-sults agree with the experimental ones. So the researchregime of AFM is enlarged from the non--contact regimeto intermittent contact regime. All of these provide theprinciple to realize manipulating single atom. |
