Effects of temperature on surface clusters by molecular dynamics simulation

Abstract

This article discusses the physical mechanisms for the evaporation phenomena of argon clusters on surfaces under various temperatures with the aid of molecular dynamics analysis by means of the Stoddard-Ford potential. Our simulated results indicate that the evaporation rate of the argon clusters increased drastically when the temperature was increased but the contact angle decreased. Furthermore, the thermal stability of the argon clusters is also discussed here. The evaporation mechanisms of argon clusters are clearly shown with the aid of molecular dynamics.
