Abstract. The growth of CaF2 on vicinal Si(111) surfaces was studied by scanning tunneling microscopy (STM) and atomic force microscopy (AFM) for the temperature range from 300 to 750C. In the submonolayer range a transition from terrace to step nucleation is observed for increasing temperature. The first monolayer grows in the step-flow growth mode since second layer islands are not nucleated before...
Abstract. The surface morphology after deposition of Ag on Ag(111) at low temperatures (130200K) has been studied in detail with SPA-LEED (Spot-Profile Analysis of Low-Energy Electron Diffraction). The surface roughness �� and the mean terrace size have been quantitatively determined under various conditions. At 130K the surface roughness �� increases with coverage exactly according to the relation...
