title = "Ultrafast electron dynamics at surfaces probed by resonant Auger spectroscopy",
abstract = "Ultrafast charge transfer processes from adsorbates to substrates are believed to occur on the timescale of (sub)-femtoseconds. In this paper we present experimental evidence for resonant tunneling of electrons at surfaces in the time regime ranging from <1 to ~50 fs. The technique used to measure these ultrafast processes is based on high-resolution spectroscopy of the decay of core-excited states. We use the natural lifetime of the core-excited states, which is on the order of a few femtoseconds for the systems investigated, as an internal clock of the adsorbate systems.",

note = "Funding Information: The work presented here is part of the Ph.D. thesis of Christian Keller. We would especially like to thank him and Markus Stichler who have obtained most of the data shown here during long hours at the synchrotron source. It was always a great pleasure to work with them. We would also like to thank Giovanni Comelli, Friedrich Esch and Silvano Lizzit from the Sincrotrone Trieste for their continuous support of our experiments and their help during data acquisition. Very fruitful discussions with Zbigniew W. Gortel are also acknowledged. Finally, financial support by the Deutsche Forschungsgemeinschaft under project Me266/22-2 and from the EC Large Scale Installation program ERBFMGETCT950022 is gratefully acknowledged.",
