6AM2-C-2 Effect of phonon-energy dissipation on friction : Nano-scale friction analysis by isotopic diamond layers

Abstract

To investigate feature of phonon energy dissipation in friction process, we compared frictions of isotopic diamonds atomic force microscope and atomic scale simulations. The friction of ^<13>C is lower than that of ^<12>C by approximately 3%. This result suggests that the lower friction of ^<13>C diamond results from the inhibition of the energy-dissipative phonon by a heavier atom mass.
