Abstract.For the first time the surface structure of an icosahedral quasicrystal has been successfully investigated in Ultra-High Vacuum (UHV) by Scanning Tunneling Microscopy (STM) and Low-Energy Electron Diffraction (LEED). After cleaning an i-Al68Pd23Mn9 sample in UHV by cycles of ion-sputtering and annealing at temperatures close to the melting point atomically flat terraces are observed by STM...
