3 - 01 : Dynamics at Surfaces and Structuring

The main focus of the present project is the geometric and electronic structure of solid and liquid surfaces and their response to excitation by femtosecond laser pulses. The research topics range from single electron dynamics at ferromagnetic metal and semiconductor surfaces to the collective response of the electronic system to intense laser excitation close to or above the ablation threshold. Thereby the coupling of electronic excitations to nuclear motion is studied following e.g. electron solvation in aqueous solutions, phase transitions in solids and at their surfaces and eventually material removal.
