Witryna18 paź 2013 · The impurity states are quasilocalized states caused by the disorder [ 16 ]. The injected electron will be reflected when its energy is equal to the energy level of the quasilocalized states; indeed quasilocalized states in disordered graphene near Dirac points have been observed experimentally and numerically [ 17 ]. Witrynathe advection 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 direct consequences on the interpretation of 1D LA-ICP-MS …
Spectral Methods of Control of Impurities, Their Flows and Localization …
Witryna1 lut 2001 · The criteria for localisation in a model that is suitable for non-interacting electrons in an impurity band is investigated. It is shown that the critical density of … Witrynalocalization of impurities within the ice crystal matrix (Figure 1). Further details of the ice core impurity imaging method have 90 already been described elsewhere (Bohleber et al., 2024). Sample selection was guided to consider ice of various depth sections and climatic periods in Antarctic ice cores, including or90scg2x1
Impurity-induced localization in cuprate superconductors
WitrynaThe improved LA-ICP-MS method for ice cores offers not only high scan speeds for single line profiles (around 1 mm s −1) but can also map the localization of impurities at high spatial resolution (35 μm), at high speed and without imaging artifacts. This promises not only new insights into the impurity distribution in glacier ice but also ... Witryna2 paź 2024 · Abstract The state-of-art of studies of processes involving small fractions of particles formed as a result of chemical transformations of the source gas or appearing from the outside as an impurity is discussed. Various high-sensitivity methods for measuring the low concentrations of particles are considered. The main focus is on … Witryna6 lis 2013 · As shown in Fig. 1a, a localized state with a finite λ −1 always gives the minimal energy Emin for any positive α, indicating that the impurity is always … portsmouth nh flowers delivery
