Abstract:
The effect of adsorbate-induced surface reconstruction on diffusion of adsorbed particles is considered in the framework of the lattice-gas model. The reconstruction is assumed to be the continuous phase transition that is described by using the phenomenological Landau theory. At low coverages (θ < 0.5), the reconstruction is shown to result in reduction of the diffusion coefficient in comparison with the value derived for the unreconstructed surface. At high coverages (θ > 0.5), diffusion is strongly anisotropic. It is facilitated in one direction and suppressed in another. The contribution of reconstruction to the apparent preexponential factor for diffusion obeys the compensation effect and is of the order of 10-2-104.
