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, … WebCharge transport in molecular systems, including DNA, is involved in many basic chemical and biological processes, and its understanding is critical if they are to be used in electronic devices. This important phenomenon is often described as either coherent tunnelling over a short distance or incoherent hopping over a long distance.

However, charge-transport modeling by itself already yields useful results, such as current-voltage characteristics and exciton generation locations. In such modeling one three-dimensionally (3D) simulates the charge transport in organic semiconductors, which takes place by hopping of charge carriers between localized sites.

WebCharge transport due to small polarons hopping among defective (bound polarons) and regular (free polarons) sites is shown to depend in a non-trivial way on the value of the stabilization energy provided by the lattice distortion surrounding the charge carriers.
