Metal-on-metal thin-film growth: Au/Ni(001) and Ni/Au(001)

Abstract
Growth modes and dynamics of vapor-deposited thin metal films on metal substrates are studied by means of molecular-dynamics simulations using embedded-atom interactions. Gold films deposited on a room-temperature Ni(001) substrate exhibit Stranski-Krastanov growth of Au(111) films, and growth of nickel films on Au(001) involves interspecies mixing and three-dimensional growth of strained films pseudomorphic to the substrate.
