- Using kinetic Monte Carlo method we simulate the dynamics of biatomic $Au_{0.3}Ni_{0.7}$ surface alloy separation on Ni(111) due to $Ni(CO)_4$ out-reaction. The experiment of Vestergaard et al. is modeled by counterbalancing dynamical processes and interactions between reactants. The simulations demonstrate step flow rate increase with CO coverage, $c_{CO},$ in qualitative agreement with the experiment only for $c_{CO}$ ≲ 0.45 monolayer. Moreover, we demonstrate both CO influence on reaction process and Au domain formation.
