"Novel Optical Studies of Ion-erosion, Growth, and Diffusion on Metal Surfaces**"Petros Thomas , University of California at Davis [Host: George Hess]
ABSTRACT:
The novel optical techniques of oblique-incidence reflectivity
difference (OI-RD) and linear optical diffraction (LOD) are applied to
several distinct surface physics problems. Studies of Ar and Ne-ion
sputtering and thermal annealing of Nb(110) and Cu(111) using OI-RD will
be discussed. The evolution of the average slope of the surface morphology
of a moderately stepped Ni(111) surface under ion erosion will be
presented. OI-RD studies of the adsorption and desorption of atomic
hydrogen and deuterium on Nb(110) and Cu(111) will also be reported."
**If time allows, the following topic will also be discussed:
"The adsorption, growth and diffusion studies of Xe on Nb(110)".
