Electron transport dynamics

In summary, the distance dependence of electron transport dynamics varies as r p, where r is the bridge length (or the number of bridge units in the case of a charge hopping process) and p is less than 2. Consequently, electron transport rates display a very weak dependence on bridge length.

The analysis above provides a typical example of how the application of a full analysis of cyclic voltammetric data may provide fine details in the description of the dynamics of electron transport and electron transfer in such complex systems.

Let us outline briefly a possible way to calculate the normal modes of a molecule, and the relation between the positions of individual atoms and collective variables. We assume, that the atomic configuration of a system is determined mainly by the elastic forces, which are insensitive to the transport electrons. The dynamics of this system is determined by the atomic Hamiltonian... 

The experimental spectroscopic methods discussed below are performed in the steady state, i.e., the time average of the nuclei positions is fixed. This justifies the use of the time-independent Schrodinger equation in the calculations. Dynamical systems are also of some interest in the context of metal-polymer interfaces in studies of, for instance, the growth process of the metallic overlayer. Also, in the context of polymer or molecular electronic devices, the dynamics of electron transport, or transport of coupled electron-phonon quasi-particles (polarons) is of fundamental interest for the performance... 

Due to the changes in the dynamics, a general relationship for stochastic dynamics is not available like it is for deterministic dynamics. However, for mesoscopic systems, a mesoscopic FR is useful. Therefore, there has been much work on developing stochastic models with different conditions. Andrieux and Gaspard developed a stochastic fluctuation relation for nonequilibrium systems whose dynamics can be described by Schnakenberg s network theory (e.g. mesoscopic electron transport, biophysical models of ion transport and some chemical reactions). Due to early experimental work on protein unfolding and related molecular motors, and their ready treatment by stochastic dynamics, a number of papers have appeared that model these systems and test the or JE for these. FR... 

We begin with a summary of the standard single-electron rigid-bridge model for electron transport [1,2], and then describe effects that arise from bridge dynamics. We next examine issues in multistep multi-center electron transfer. The closely related problem of two-electron transfer is then discussed. Multi-center and multielectron processes are of great relevance for ET in DNA, proteins, and catalytic reactions.
