Activated conduction in microscopic molecular junctions

Article Abstract:

Issues concerning the relationship between the steady state electron transfer rate that is the central observable in electron transfer measurements and the conduction of a junction based on the same molecular bridge are discussed.

Electron transfer rates in bridged molecular systems 2. A steady-state analysis of coherent tunneling and thermal transitions

Article Abstract:

A simple molecular model is used to investigate how bridged molecular systems are affected by dephasing and relaxation on electron transfer. The Redfield theory is used to describe the interaction between the molecular system and its thermal environment.

Tunneling time for electron transfer reactions

Article Abstract:

The tunneling time for nonadiabatic electron transfer reactions described within the superexchange model is estimated using a Buttiker type internal clock: the electron is taken to possess two internal spin states that are weakly coupled on the bridge. Study relating to the determination of traversal time through the bridge is presented.
