Off lattice Monte-Carlo simulations of low-dimensional surface defects and metal deposits on Pt(1Â 1Â 1)

In order to contribute to the understanding of metal electrodeposition on real surfaces, we consider in the present work the deposition of Ag, Cu and Pd on a Pt(1 1 1) surface with defects. Off lattice Monte-Carlo simulations were performed using embedded atom method Potentials in the canonical ensemble at 300 K. Structural and energetic properties of deposits on surface defects of low dimension (iD = 0, 1, 2) were studied. Among others, we consider vacancies (0D), steps (1D) and holes (2D). The results obtained are in qualitative agreement with experimental data in the literature.
