WebAug 10, 2024 · In contrast to the energy migration over distances below R 0, we assign this additional long-range pathway to an incoherent energy hopping process as it has been previously proposed for triplet energy hopping 12 or experimentally observed for long-range charge hopping through DNA. Figure 2. WebJun 18, 2009 · A new quantum dynamic equation for excitation energy transfer is developed which can describe quantum coherent wavelike motion and incoherent …
WebAbstract We assess the validity of incoherent hopping models that have previously been used to describe electron transport in crystalline C 60 at room temperature. To this end we present new density functional theory based calculations of the electron transfer parameter defining these models. WebIn general, the resistance of DNA increases linearly with length, as expected for incoherent hopping. However, for DNA sequences with stacked guanine-cytosine (GC) base pairs, a periodic oscillation is superimposed on the linear length dependence, indicating partial coherent transport. This result is supported by the finding of strong ...
WebApr 28, 2015 · Quantum transport in disordered systems is studied using a polaron-based master equation. 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. WebMay 4, 2024 · We demonstrate that efficient and nearly field-independent charge separation of electron-hole pairs in organic planar heterojunction solar cells can be described by an incoherent hopping mechanism. Using kinetic Monte Carlo simulations that include the effect of on-chain delocalization as well as entropic contributions, we simulate the ...
