Diffusion of H atom in the Ti(0001) outer-layer and inter-layer surface is studied using density functional theory … based on generalized gradient approximation (GGA). The energy barriers for the hydrogen atom diffusion in different … diffusion in the adjacent interstitial layers are bigger than that in the same interstitial layers. For the diffusion of H atom …

Since this is based on the concept of "diffusion toward electrode surfaces", detectable scale … depends on the diffusion coefficient, and it is in the range of 1–100 μm for conventional electrochemistry. By taking this … diffusion. Thus, the detectable fractality scale, which is proportional to the square root of diffusion coefficient, can be …
