Localization of electrons

Witryna1 gru 1993 · The present review aims to fill the niche for a non-specialized review of this very active area of research. The basic concepts behind the theory are introduced with more detailed sections covering experimental results, one-dimensional localization, scaling theory, weak localization, magnetic field effects and fluctuations. WitrynaThe question is: how should we describe the electron states in an assembly of `atoms' with overlapping bound-state wave functions? In a regular lattice, these states are non-localized Bloch functions, forming a band of width B, say. Attention is focused on the effects of `cellular disorder', where a statistical variation wl is imposed on the energy …

Witryna11 kwi 2024 · In quest of a controllable intramolecular electron transfer (ET) across a bridge, we study the cation-radical form of the parent 1,4-diallyl-butane (I) and its derivatives (II)−(VI). In these mixed-valence (MV) compounds, the bridge of variable length connecting allyl redox sites can be either saturated (−CH2 CH2−) (I, III, and V) … Witryna9 maj 2024 · Even if these additional SEs are created at some distance from the adatom, atomic resolution can still occur, being determined by the degree of localization of the primary-electron scattering. Figure 4b suggests that FSE with E se ≈ 700 eV can liberate as many as seven secondaries from an alumina substrate.
