✦ Synopsis

Using a properly chosen master equation describing combined desorption and surface diffusion processes in interacting adsorbate layers, we analyze the coverage evolution and calculate the dynamical structure factor for the adsorbate in the weak intra-adsorbate interaction limit. The connection with formerly analyzed desorption-diffusion processes in noninteracting adsorbate is made. For a simplified one-dimensional model the analytically derived expression for the dynamical structure factor permits discussion of its dependence on sign of the interactions and value of the desorption rate.
