Molecular Dynamics Simulation on Nano-indentation of Self-Assembled Monolayers

Molecular dynamics simulations have been used to study the nano-indentation of CH 3(CH 2) 15S self-assembled monolayers on Au(111). The results showed that jump to contact occurred under the action of Au tip. Furthermore, the hysteresis of the tilt angle and lateral load of the monolayers was observed, which was attributed to the adhesion between the tip and the self-assembled monolayer.
