Abstract
We study the diffusion process of interacting Brownian particles on stepped surfaces. By employing the Langevin dynamic simulation we have calculated the diffusion coefficient D as a function of the concentration c for different values of the correlation lengths. Our results show that, on stepped surface, the diffusion process is reduced with respect to the one corresponding to the flat surface.
