Outline of Final Research Achievements

We have established a new method to simply estimate surface diffusion coefficients which is difficult to measure in experiments. The method is based not on the conventional molecular dynamics calculations, but on the approximation from density functional theory and transition state theory. We have also performed sophisticated multi-scale analysis including all of convective gas diffusion, surface diffusion, adsorption, desorption, surface reaction and charge transfer. The analysis can help us to clarify specific phenomenon near triple-phase boundary where mass transport and reaction are complicated.
