Molecular-dynamics simulations with a corrected-effective-medium potential have been applied to study the kinetics of intermixing in Au/Ag(110) heteroepitaxy. Significant intermixing of Au and Ag at the interface has been observed at room temperature. A variety of interesting kinetic mechanisms have been revealed. Our study demonstrates that the kinetics of intermixing have a complex dependence on the local geometry of the Ag substrate, Au-Au interactions, and a long-range coupling of adatom motions via adsorbate-induced relaxation of the surface atoms.
