| Outline of Final Research Achievements |
We have studied the relation between the dynamical friction and the surface structure/the mobility of surface molecules by simultaneous measurement of the energy dissipation and topography images. We found as follows: 1. the energy dissipation increases at the step structure of HOPG when the sliding distance is larger than the lattice constant. 2. the friction on MoS2 submicron islands drastically due to the phonon confinement. 3 the energy dissipation of Au surface shows a large temperature dependence from room temperature down to LN2 temperature. Especially, from the present study, we demonstrate that the superlubrication can be realized by phonon confinement.
