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...
