For submonolayer nucleation and growth of islands during metal (100) homoepitaxy, we precisely characterize transitions, with increasing temperature, in the critical size, i , above which islands are effectively stable. For strong adatom bonding, we

We present the variation of the activation barriers with the number of movable substrate atoms for the self-migration of adatoms on fcc (001) surfaces. Two mechanisms considered in this paper are: (1) hopping of the adatom from one four-fold hollow s

We present activation barriers and prefactors for the migration of heterogeneous adatoms on fcc(100) surfaces. Two mechanisms are considered in this paper: (1) hopping of the adatom from one four-fold hollow site to an adjacent four-fold hollow site

We investigate the mechanisms and associated energies of diffusion for the Ni Ni(110) , Cu Cu(110) , Pd Pd(110) and Ag Ag(110) systems using the corrected effective medium (CEM) method. On the (110) surface, cross-channel diffusion can occur via atom

We investigate the mechanisms and associated energetics of diffusion for the Ni/Ni(100), Cu/Cu(100), Pd/Pd(100) and Ag/Ag(100) systems using the corrected effective medium method. The Ni/Ni(100) and Cu/Cu(100) systems are shown to favor the atomic-ex

We present the first version of SCT89, a general user-friendly program for performing molecular dynamics simulations of processes on metal surfaces. Incorporation of the recently developed MD/MC-CEM potential energy surface allows us to consistently
