Abstract

3/2 for sufficiently large N. The latter feature is expected from continuum Langevin formulations appropriate for large sizes. We compare predictions from our model incorporating appropriate energetic parameters for Ag(100) with different sets of experimental data for diffusivity at 300 K, including assessment of beta(eff), for experimentally observed sizes N from similar to 100 to similar to 1000.
