Main Focus

  • Low temperature scanning tunneling microscopy (4K-STM)
  • STM-induced luminescence on organic molecules and local exciton spectroscopy
  • Fast STM-controlled processes monitored through light emission

  • sum-frequency spectroscopy in vacuum and in the electrochemical cell
  • magnetism of ultrathin alloys
  • design of an infrared-visible sum-frequency imaging microscope
  • vibrational energy transfer at surfaces
  • elastic and inelastic thermal Helium beam scattering
  • surface reconstructions and interaction with adsorbates
