Moiré-regulated composition evolution kinetics of bicomponent nanoclusters

A simple model and computation of Moiré-regulated composition evolution kinetics of bicomponent nanoclusters is presented. Assuming continuous adsorbate coverage on top of 2D bilayer and Moiré potential-driven nanocluster formation at fcc sites of Moiré landscape, these sites experience the influx of one component of a bicomponent adsorbate and the outflux of another component. Kinetics of this process is characterized for several combinations of adsorption potentials and their relative strengths.
