WebMay 20, 2024 · As discussed, ET in biological systems is usually described by the incoherent hopping process. While switching from biological systems to conductive synthetic systems, such as conductive polymers or organic semiconductors, both hopping and coherent transport are used to describe ET [28–30].In general, the hopping mechanism is used to …

WebMar 5, 2014 · The second type of elementary process is the incoherent hopping from to , represented by the operators. Any channel that can be described as an average over products of these two types of operators has to be considered incoherent, and a proper measure of coherent delocalization must never increase under such a channel. WebThe proposed mechanism explains how spin-polarization emerges in systems where charge transport is dominated by incoherent hopping, mediated by spin-orbit and electronic exchange couplings through an intermediate charge transfer state. grandtic 国富

WebOct 21, 2013 · The polaron approach is capable of bridging the results from the coherent band-like transport regime governed by the Redfield equation to incoherent hopping transport in the classical regime. Additionally, a non-monotonic dependence of the diffusion coefficient is observed both as a function of temperature and system-phonon coupling … WebSep 8, 2016 · Although the later time scales of charge separation have been successfully described by incoherent hopping 7, a consistent model at the earliest time scales, describing the coherent propagation of ...
