Photo-Induced Non-Equilibrium Dynamics of Adsorbates on Metal Surfaces

Abstract

The resonance state localized on adsorbate has been shown to play a crucial role in photo-induced adsorbate dynamics. The observed non-equilibrium dynamics in hot-carrier induced desorption of CO on Cu (100) has been understood from the temperature- and mode-dependent friction coefficients deduced from the position and lifetime of the lowest-lying 2π resonance of CO molecule.
