Kurzbeschreibung (Abstract)
Fundamental insights into the ultrafast dynamics of energy transfer processes at surfaces are of central importance for a microscopic understanding of chemical reactions at solid surfaces, e.g. in heterogeneous catalysis. The detailed investigation of the rates and pathways of energy flow in the adsorbate–substrate system as well as the chemical dynamics has become possible utilizing intense femtosecond laser pulses. Surprisingly, the strong non–equilibrium situation that arises upon irradiation with these pulses results in a new reaction channel caused by hot electron excitation for a number of systems investigated. This electron–mediated reaction mechanism is exemplified here for the model reaction Had+Had → H₂,g on Ru(001) and discussed in the broader context of other simple reactions such as the formation of H₂O, CO₂ and the CO desorption on the same surface.
