    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...

    Photoemission and scanning tunneling experiments with small particles on solid surfaces

    The fascination of research with nanometersized objects in contact with a macroscopic surface will be illustrated by two examples: mass-selected supported transition-metal clusters and C60 molecules on metallic s...

    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...

    Surface effects in Dy, DySb and DyTe observed by photoelectron spectroscopy

    Cold condensed (100 K) Dy-films, as well as DySb and DyTe were studied by photoelectron spectroscopy using HeII and HeII* excitation sources. The spectra were analyzed using the relative intensities and energy sp...

    High-Resolution Photoemission Study of the Low-Energy Excitations Reflecting the Superconducting State of Bi-Sr-Ca-Cu-O Single Crystals

    uv-photoemission spectra (hv=21. 2 eV) of single-crystal specimens of the high-Tc, superconductor Bi2Sr2CaCu 2O8 have been measured with a resolution of 20 meV in the normal state at 105 K and in the superconduct...

    Electronic Structure of Deposited Mass-Selected Pt Clusters on Silver Films

    The knowledge of electronic structure as a function of cluster size is crucial for the understanding of many properties of condensed matter at the nanometer scale such as the metal-insulator transition, the be...

    Photoemission from Size-Selected Pt-Clusters Deposited on Silver Films

    When atoms are brought close together to form a solid their outer wave functions overlap and the energy levels of the individual atoms broaden and become the energy bands of condensed matter. The observation o...
