摘要: Molecular dynamics simulation is used to study nanoindentation of the self-assembled monolayers (SAMs) on an Au surface. The interaction SAM atoms described by a general universal force field (UFF), tight-binding second-moment approximation (TB-SMA) for substrate, and Lennard-Jones potential function employed describe among indenter, SAMs, substrate atoms. model consists planar with n-hexadecanethiol chemisorbed substrate. results show that contact pressure increases as SAMs temperature increases. In addition, also depth velocity indentation increase.
