Submonolayer Island Formation and Subsequent Multilayer Kinetic Roughening During Metal(100) Homoepitaxy: Fe, Ag & Cu
Initial island formation and multilayer kinetic roughening observed during Fe/Fe(100), Ag/Ag(100) and Cu/Cu(100) homoepitaxy are analyzed utilizing an appropriate lattice-gas model. The model includes nucleation and growth of two-dimensional near-square islands in each layer, downward funneling of deposited atoms to four-fold hollow adsorption sites, and an additional step-edge barrier for interlayer transport. Key energies are predicted.
