摘要
A high-fidelity kinetic Monte Carlo (KMC) simulation method (T. Treeratanaphitak, M. Pritzker, N.M. Abukhdeir, Electrochim. Acta 121 (2014) 407-414) using the semi-empirical multi-body embedded-atom method (EAM) potential has been extended to model polycrystalline metal electrodeposition. Simulations using KMC-EAM are performed over a range of overpotentials to predict the effect on deposit texture evolution. Roughness-time power law behaviour (proportional to t(beta)) is observed where beta = 0.62 +/- 0.12, which is in good agreement with past experimental results. Furthermore, the simulations provide insights into the dynamics of sub-surface deposit morphology which are not directly accessible from experimental measurements. (C) 2014 Elsevier B.V.
