Initial stages of Lutetium growth on Si (111)-7 x 7 probed by STM and core-level photoelectron spectroscopy

Original language description

The interaction of small amounts of Lutetium with the Si (111)-7 x 7 reconstructed surface was investigated in detail using a combination of Scanning Tunneling Microscopy (STM) and Photoelectron Spectroscopy (XPS and UPS). Various immobile and also fastly moving atoms and nanocluster were found in the initial growth of the Lu/Si interface. Density functional theory calculations and photoelectron spectroscopy results suggest that the most attractive adsorption sites for the Lu atoms are basins around Si rest-atoms and there is no strong interaction between Lu and Si at the initial steps of film growth. However Lu nanocluster could also be found on other adsorption sites which results in a different voltage dependence in STM. Coverage-dependent STM images reveal the growth of a closed Lu metal overlayer by joining of the clusters. The existence of a stoichiometric Lu silicide compound was not detected on the surface in the initial growth for deposition at room temperature.
