Abstract

Abstract In this paper, a molecular dynamics simulation has been used to study the nanotribological properties of the molecular deposition film deposited on the Au (111) substrate during the scan process with an Au tip. The results show that the tilt angle and the potential energy of the molecules near the tip are both increased with decreasing distance between the tip and monolayer. Continuous slip also occurs during the slip stage. Furthermore, the regular stick-slip is in agreement with the spatial structure.
