Abstract

Motivated by recent progress in producing metastable metallic binary alloy films and nanoclusters through atomic deposition techniques, we propose a simple, analytically solvable model of a growing Ising-type one-dimensional chain whose kinetics are determined by random addition of two atomic species and by compositional relaxation restricted to the surface. Solutions are presented for the influence of the external flux on both surface segregation and compositional short-range correlations in the bulk, which is frozen. Despite the simplicity of the model, these results can help to understand opposing trends in surface segregation and bulk short-range order, revealed in recent experiments and simulations for fcc-type nanoalloys.
