Witrynation of impurity anomalies, through diffusion along the ice vein network, has been discussed as a possible cause of post-depositional alterations in ice core paleoclimate records (Rempel et al., 2001; Ng, 2024). Impurity localization at the grain boundaries also has di-rect consequences on the interpretation of 1-D LA-ICP-MS WitrynaThe localization in a disordered metal by means of the perturbation approach is considered. It is shown that in the case of a given impurity potential a small disorder leads to localization in 2D as well as in 1D and causes the weak localization in 3D. In contrast, in the case of the impurity potential screened by electrons (interacting …
