Abstract(in English) | Variable Temperature Scanning Tunneling Microscope(VT-STM)allows us to study annealing process of the damage caused by ion impact. A Si(111)surface irradiated by Xe ion, with Va=1kV and Dose-6.4×10^12 ions/cm^2, was observed by VT-STM. The disordered image was obtained at room temperature after irradiation. Many redeposited Si atoms and several vacancy clusters were found on the surface. When it was observed by VT-STM at 600℃, some fragments of the 7×7 structure and vacancy clusters remained on the surface. At this temperature, only atoms on bondary between vacancy cluster and 7×7 structure could move, but the large vacancy clusters didn't move. These indicate that redeposited Si atoms move fast , but vacancies move very slow on surfaces at 600℃. |
