    Model potential for the description of metal/organic interface states

    We present an analytical one-dimensional model potential for the description of electronic interface states that form at the interface between a metal surface and flat-lying adlayers of π-conjugated organic molec...

    Reaction Dynamics of Molecular Hydrogen on Silicon Surfaces: Importance of Lattice Degrees of Freedom

    Hydrogen dissociation on silicon surfaces is strongly activated both by kinetic energy of the H2 molecules as well as by surface temperature. The latter effect is correlated to the covalent nature of the Si–Si an...

    Ultrafast dynamics of photoinduced processes at surfaces and interfaces

    While femtochemistry in the gas and solution phase has led to enormous progress in the understanding and even control of chemical reactions over the past decades, a comparable level of sophistication in the an...

    Reptilienschutz

    Reptilien sind Teil einer Faunengruppe, deren Lebensraum kontinuierlich eingeengt wurde und die seit Menschengedenken unter aktiver Verfolgung zu leiden hat. HEDIGER schrieb 1937 in seiner Abhandlung „Die Schl...

    Dephasing of Image-Potential States on Cu(100) upon CO Adsorption Measured by Femtosecond Two-Photon Photoemission Spectroscopy

    The relaxation dynamics of the image-potential states of Cu(100) under the influence of CO adsorption is investigated by time-resolved Two-Photon Photoemission Spectroscopy (2PPE). Pure dephasing due to elasti...
