Abstract

Time-resolved two-photon photoemission (2PPE) spectroscopy was used to study the dynamics of image potential states at Cu(100) surfaces. First-order perturbation theory was used to compute 2PPE spectrum and to study the populations of image potential states as a function of lifetime and dephasing of image potential states. It was found that a change in dephasing parameters did not affect the population densities of the image potential states. The analysis suggested that the proposed method efficiently described the dynamics of image potentials of metal-molecule-vacuum interfaces.
