Abstract
In this paper we study the relationship between equilibrium and kineti cs in Cu-Ag (111). We investigate the kinetics of segregation in a sil ver-dilute-copper sample and the dissolution kinetics of one Ag monola yer deposited on Cu(111). We compare results obtained using mean-field and Monte Carlo methods and relate them to the equilibrium isotherm b y means of a local-equilibrium concept. We find good agreement with av ailable experimental results on segregation kinetics and on dissolutio n kinetics when the Monte Carlo simulation is used.
