Electron–Phonon Coupling Effect on Charge Transfer in Nanostructures

Two simple quantum electron networks are considered: one has an interference structure, and one is a simple chain. The network is coupled at one edge site to a metal reservoir that works as a sink for arriving charges. When the electron reaches the edge site and has an energy at or above the Fermi level of the metal sink, we assume that it will be absorbed. The adiabatic electron phonon coupling will lower the energy level of the last site (before the sink) when the electron enters it. When this polarization-corrected energy is lower than the Fermi level, the absorption into the sink has to be activated above the metal Fermi sea and the absorbing rate will be slowed down.
