Incoherent hopping
WebNov 3, 2024 · We show how the hopping process may create excitations when starting from a state with a finite excitation density. That is, how hopping can change the state of a … WebInstead, charge carriers are localized at molecular entities, e.g. oligomers or segments of a conjugated polymer chain and move by incoherent hopping among adjacent sites with statistically variable energies. Quite often the site energies feature a Gaussian distribution. Also the hopping distances can vary statistically (positional disorder).

WebApr 10, 2024 · But there was thought to be no coherence – no in-phase resonance – in this coupling. Instead, the energy transport was pictured as a random (incoherent) hopping process between chromophores, guided by an overall energy gradient, like a drunken sailor staggering downhill. WebHopping is an incoherent, thermally activated process in which an electron moves from one site to another but loses all information about its phase in the process. In other words, there is no coherence between the amplitudes for finding an electron at different lattice sites.
