    The reactivity of gold and platinum metals in their cluster phase

    Platinum surfaces are known to be among the most active ones for the oxidation of carbon monoxide, whereas gold surfaces are completely inert for this reaction. The question remains: Do small clusters of these...

    Surface-state linewidth from scanning tunnelling spectroscopy

    The STM can be used to investigate lifetimes of hot holes in a surface state at low temperatures. We analysed dI/dV data from Ag(111) using detailed tunnelling calculations and a simple model and found an electro...

    Stability of two-dimensional nanostructures

    We investigate atomic and molecular nanostructures on metal surfaces by variable low-temperature scanning tunnelling microscopy. In combination with molecular dynamics calculations we achieve a detailed unders...

    Size-dependent light emission from mass-selected clusters

    The emission of photons in the visible wavelength range from mass-selected Ag+ n, Cu+ n, Pt+ n and Pd+ n ( ) clusters is observed. Photons are detected ...

    Photon emission from adsorbed C60 molecules with sub-nanometer lateral resolution

    We present the first experimental demonstration of spatially resolved photon emission of individual molecules on a surface. A scanning tunneling microscope (STM) was used as a local electron source to excite p...

    Internal structure of C60 fullerence molecules as revealed by low-temperature STM

    We have performed Scanning Tunneling Microscopy (STM) in ultra-high vacuum at low temperatures (5 and 50K) of unordered and ordered C60 layers adsorbed on a Au(110) surface. STM topographs of the frozen C60 molec...
