Polaron formation: Ehrenfest dynamics vs. exact results
Guangqi Li, Bijan Movaghar, Abraham Nitzan +1
We use a 1-dimensional tight binding model with an impurity site characterized by electron-vibration coupling, to describe electron transfer and localization at zero temperature, a…
Yield of exciton dissociation in a donor-acceptor system
Guangqi Li, Abraham Nitzan, Mark A. Ratner
A simple model is constructed to describe dissociation of charge transfer excitons in bulk heterojunction solar cells, and its dependence on the physical parameters of the system.…
Compensation of Coulomb blocking and energy transfer in the current voltage characteristic of molecular conduction junctions
Guangqi Li, Manmohan S. Shishodia, Boris D. Fainberg +2
We have studied the influence of both exciton effects and Coulomb repulsion on current in molecular nanojunctions. We show that dipolar energy-transfer interactions between the sit…
