WebJun 21, 2009 · A new quantum dynamic equation for excitation energy transfer is developed which can describe quantum coherent wavelike motion and incoherent hopping in a unified manner. The developed equation reduces to the conventional Redfield theory and Forster theory in their respective limits of validity.

WebThe concept of hopping transport has been familiar for a long time in connection with ionic conduction, since ions move essentially by hopping, whether through interstices or vacancies. This concept has been extended to electrons, particularly for electronic conduction in amorphous and disordered nonmetallic solids. 4, 34 WebJul 8, 2015 · Exclusively incoherent hopping cannot account for our observations; however, fully coherent transport is also unlikely at room temperature 17,28. We therefore suggest a combined coherent ...
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.

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…
