Evaluation of Diffusion Coefficients from Composition Profiles - The Influence of Trapping
The applicability of the Boltzmann-Matano method for evaluation of a diffusion coefficient and its concentration dependency by line profile analysis is tested on three different (model) systems. All systems involve interstitial diffusion. It is shown that the occurrence of trapping corrupts the applicability of the Boltzmann-Matano method.
