Witryna11 kwi 2024 · As is known, the interaction between the electron and the impurity creates a localized state in the band gap of the semiconductor material. This gives the opportunity to investigate one of the optical properties—that of the impurity photoionization cross-section. The process of photoionization occurs when a photon … 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
