The Interaction of UV-Laser Radiation with Metal and Semiconductor Surfaces
Abstract
This report describes progress in a program to understand the fundamentals of UV laser interactions with solid surfaces. In the first, using the previously developed optical probes, we have made the first measurements of the surface photo- dissociation cross section, its yield, its wavelength dependence, and its dependence on surface conditions for two important metal- alkyl precursors. Second, we have successfully initiated a substantial new program in UV-laser photoemission for surface probing. This work has included establishing a new, tunable, two-photon photoemission apparatus including UHV chamber with an electron detection system,demonstration of a new technique to probe buried interfaces, the use of high-resolution, two-photon spectroscopy to probe surface-condition-dependent changes via image states, and the observation of space-charge-limited effects on surface photoionization spectroscopy.
