The dynamics of vibrational healing 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 O 2 desorbed from Pt(111) by femtosecond laser pulses. The subpicosecond response time of the desorption probability is shown to arise directly...
Vibrational heating of a surface bond by a hot electron gas is investigated with a quantum-mechanical model and its classical limit. It is shown, for a model system CO/Cu, that the quantum-mechanical description is important to correctly describe the multi-vibrational excitation at low temperature T v , where k B T v ≤ħω, the vibrational energy quantum. The subpicosecond response...
