| Abstract: | The dynamics of vibrational heating and desorption induced by multiple inelastic hot electron scatterings is investigated by a microscopic quantum mechanical approach. Numerical simulations are found to be in good agreement with experimental results of O2 desorbed from Pt(111) by femtosecond laser pulses. The subpicosecond response time of the desorption probability is shown to arise directly from the dynamics of vibrational heating of the molecule-surface bond. |
