In order to dynamically clarify the friction mechanism between specimen surface and probe tip in the surface observation by atomic force microscope (AFM) or friction force microscope (FFM), several molecular dynamics simulations were performed. In the simulation, a 3-dimensional simulation model is proposed where the specimen and the probe are assumed to consist of mono-crystalline copper and rigid diamond or carbon atom, respectively. The effect of cantilever stiffness of AFM/FFM is also taken into considered. The surface observation process on a well-defined Cu {100} is simulated. From the simulation results, it was proven that even when the probe with the flat tip was used, the atomic image can be observed due to the periodicity of the specimen surface atomic arrays.
