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. small assisted living coalition tampa

"WebFeb 28, 2005 · Conclusions. The electronic structure of FL oligomers provides a means to access the wire-like incoherent hopping regime for hole transport over long distances at nearly constant bridge energy. This property is a consequence of the localization of charge at the two terminal monomers within the F L n + ∙ bridge. " - Incoherent hopping

Crystalline solids and molecular solids are two opposite extreme cases of materials that exhibit substantially different transport mechanisms. While in atomic solids transport is intra-molecular, also known as band transport, in molecular solids the transport is inter-molecular, also known as hopping transport. The two different mechanisms result in different charge mobilities. In disordered solids, disordered potentials result in weak localization effects (traps), which reduc…
