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 ($\propto t^\beta$) is observed where $\beta=0.62 \pm 0.12$, 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.
