Abstract
A new atomistic simulation model for electrochemical systems is presented. It combines microcanonical molecular dynamics for the electrode with stochastic dynamics for the solution, and allows the simulation of electrochemical deposition and dissolution for specific electrode potentials. As first applications the deposition of silver and platinum on Au(1Â 1Â 1) have been studied; both flat surfaces and surfaces with islands have been considered. The two systems behave quite differently: Ag on Au(1Â 1Â 1) grows layer by layer, while Pt forms a surface alloy on Au(1Â 1Â 1), which is followed by three-dimensional growth.
