The Mean Trajectory Approximation for Charge and Energy Transfer Processes at Surfaces.

Abstract

We discuss electronic energy and charge transfer processes at surfaces in terms of curve crossing models. We suggest that at low kinetic energies the trajectory approximation should be replaced by a mean trajectory approximation (MTA), in which the nuclear motion gets feedback from and adjusts to the curve crossing dynamics. We discuss two derivations of MTA by using an eikonal approximation and a path integral method. The effects of phonon or electron-hole pair excitations on the charge transfer process are also incorporated.
