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. 收起
