Abstract

The fast diffusion of hydrogen in thin Yttrium/Vanadium (Y/V) bilayers where H mobility was varied locally by adjusting the Y/V thickness ratio was discussed. It was found that Y/V bilayer offered the possibility to tune and to visualize solid state diffusion in a 2D system. The numerical simulations based on individual random walkers, representing the diffusing H particles were studied. Analysis shows that the diffusion front of the simulation using random walkers resembled to a large extent the H diffusion experiment.
