Surface self-diffusion is also included in the analysis.
From the growth model, we noticed a significant change in the surface self-diffusion rate of indium adatoms.
For the first time, an anomaly of the surface self-diffusion coefficient of Fe below the Curie temperature was observed (magnetic effect for the surface diffusion).
60 (2012) 123–130], the self-diffusion coefficient of Cu along the Cu–W interface at 1000 °C was estimated at (3.3 ± 0.8) × 10−9 m2 s−1, which is comparable to the surface self-diffusion coefficient of Cu at the same temperature.
These processes can be analyzed in terms of an effective self-diffusion coefficient (Deff).
The effective surface diffusion coefficient Deff (observed) is modified from Dm due to the finite residence time on the surface.
When the surface diffusivity equals the self-diffusion coefficient, (omega = 1).
The delicately designed core-shell heterostructure takes advantage of the high effective surface area, facile electrolyte diffusion and fast electron transfer.
When effective diffusion coefficients are converted to solvent self-diffusion coefficients, the values are 30-fold lower than NMR values at low concentrations, taken as a measure of tortuosity, but closely approach NMR values above the transition.
They incorporate viscous flow with slip boundary, molecular diffusion (i.e. molecular self-diffusion), Knudsen diffusion, and surface diffusion in the adsorption layer.
