摘要：

In this work, we present results of an extensive Monte Carlo study of the O/W(110) system under non-equilibrium conditions. Through studies of the long wavelength density fluctuations of adatoms, we define an effective and time-dependent value for the collective mobility, whose behavior is studied during the non-equilibrium process. We discuss our results in view of existing experimental measurements of effective diffusion barriers, and the difficulties associated with interpreting non-equilibrium data.
