In dieser Arbeit wird das Konzept und die experimentelle Umsetzung einer neuartigen
Kombination aus Tieftemperatur-Rastertunnelmikroskop und fs-Lasersystem zur …

Der Energietransfer zwischen Metallsubstrat und Adsorbat findet, vermittelt durch Elektronen
und Phononen des Substrats, auf einer ultraschnellen Zeitskala statt. Mechanismen und …

We investigate two fundamental steps of a nonadiabatic surface process, the photo-induced
movement and approach of CO molecules on the Cu (111) surface, at a hitherto unachieved …

Zielsetzung Molekulare Prozesse, wie Dissoziation, Diffusion und Desorption an
Oberflächen können sowohl thermisch als auch athermisch ausgelöst werden. Diese Arbeit …

A combination of femtosecond laser excitation with a low-temperature scanning tunneling
microscope is used to study long-range interaction during diffusion of CO on Cu (111). Both …

Lateral hopping and desorption of a single CO molecule on a Cu (110) surface [Bartels,
Science 305, 648 (2004) SCIEAS 0036-8075 10.1126/science. 1099770] induced by …

Carbon monoxide on copper surfaces continues to be a fascinating, rich microlab for many
questions evolving in surface science. Recently, hot-electron mediated, femtosecond-laser …

The structure of D 2 O clusters on a Cu (111) surface and the femtosecond dynamics of
photoexcited excess electrons are investigated by low-temperature scanning tunneling …

The laser-induced desorption of CO molecules from a Cu (111) surface is time resolved with
100-fsec resolution. We find the desorption reaction is completed in≤ 325 fsec after the 100 …

Desorption of CO from Cu (100) by femtosecond laser pulses was investigated using state
and time-resolved techniques. The results are well described by two models based on …
