Thin layers of LiF deposited on Si(100) single crystal were investigated by ESD, LEED, AES and AFM. The results show that the surface morphology strongly influences the kinetic energy distributions of desorbed ions in ESD experiments. LiF deposited at elevated temperatures or at room temperature and subsequently annealed forms preferentially 3D islands leaving uncovered Si areas between them. Annealing...
The change of atomic structures and compositional ratios by isochronal annealing of Ag-Ni binary adsorbates at the Si(111) surface has been studied by means of LEED-AES-RBS techniques at temperatures from 200°C to 700°C. It is found that the surface coverage of Ni deposited on the Si(111)-√3 √3-Ag surface decreases to 0 ML on annealing at 250°C for 15 min, while the Ag surface coverage is not changed...
