Query: Monte Carlo Simulation of Surface De-alloying of Au/Ni(110)   Based on BFS model and using Monte Carlo simulation we confirms the
de-alloying in immiscible Au/Ni(110) system, and the critical Au coverage when
de-alloying happens is also consistent with experiments. At the same time our
simulation show that the structural phase transition will lead to the
saturation of the number of alloying Au atoms.
