Notes:
Diffusion coefficients are examined in interactive models by using different methods and different overlayer configurations. Comparison between the fluctuation and laser-induced-desorption method on well-equilibrated overlayers can lead to large differences depending on the ordered structures formed. If comparison is made between well-equilibrated and faraway-from-equilibrium configurations different diffusion coefficients and activation energies are obtained. Finally, the activation energy ΔEc obtained from growth rates in coarsening experiments is shown to verify ΔEc=xΔEd, where x is the growth exponent and ΔEd the activation energy of diffusion.
