Molecular-Dynamics Study Of Self-Diffusion: Of The Au4;Au4/Ag(110) System

Abstract

Abstract In this work, we will shed light on the results obtained from the molecular dynamics method in the temperature ranging of 300-700K. This investigation concerning the coalescence for the two tetramers islands of system having different forms (SS, TT and NN) deposited at different spacing sites in-channel and cross-channel. The stability of the systems, the diffusion phenomena produced during the dynamics, as well as the diffusion/coalescence lifetime during the evolution of temperature are dependent. The dynamic study shows that between 450K and 650K the homogeneous partial coalescence occurs through the mechanism of the jump. As time goes by increasing the temperature which favors the process of exchange the heterogeneous total coalescence is obtained.
