摘要: This article sheds light on the investigation of diffusion and adsorption Pt Au adatoms ideal (1 × 1) missing-row structures ((1 × 2), (1 × 3), (1 × 4)) Pt(110) surfaces. study is performed by using quenched molecular dynamics simulations combined with an interatomic potential derived from embedded-atom method (EAM). For each geometry, we have considered homo- heterogeneous systems: Pt/Pt Au/Pt. The multilayer adatom relaxation trends bond lengths first nearest neighbors were examined. We found that atomic quantitatively different for all configurations. static energy barriers hopping calculated configurations both systems. Thus, analysis our results provides interesting insights a tentative idea about geometry influence reconstructed Our numerical compared some experimental theoretical data available in literature good agreement was achieved.
