Effects of Lattice Steps on Diffusion and Epitaxial Growthso the dynamic behavior of the surface at elevated temperature. We will discuss how atoms move and bind at step edges, how atoms can diffuse across and along lattice steps, and how these atomic processes can affect the growth process and the structure in thin film epitaxy.

Scanning Tunneling Microscopy Study of Single Pb Atom Diffusion on Si(111)7×7 and Si(111)5×5 SurfaceThe diffusion of single Pb atoms on Si(111)7×7 and Si(111)5×5 surfaces has been investigated in real time by scanning tunneling microscopy (STM). The STM results show that single Pb atoms are highly mobile at room temperature inside (7×7) or (5×5) half-cells but diffuse at very low rates to neighbor half-cells.

Atomic Mobility of Ag and Fe on the Ag(100) Surface temperature for Ag adatom diffusion on Ag(100) to be 160(5) K. From this value we estimated the activation energy barrier for self-diffusion on Ag(100) to be 0.40(5) eV. Single Fe adatoms on the Ag(100) surface were found to exchange site with Ag atoms from the first layer, starting at a temperature of 130(10) K.
