The Interaction of Ultraviolet Laser Radiation with Metal and Semiconductor Surfaces
Abstract
The work during this contract period focused on phenomena at nanostructured metal and semiconductor surfaces, which are probed using short-pulse photoemission. Specifically, the program was to investigate the low-dimensional quantum confinement of electrons on spatially-patterned surfaces of single-crystal metals. It also aimed to expand the applications, the technique, and the instrumentation for nonlinear optical techniques of surface electrons. Electronic systems of reduced dimensionality are of interest for a variety of applications for electronic devices. In addition, the thin-film metallic structures that are currently under discussion for magnetic-memory applications, also utilize quantum confinement This investigation has focused on the use of excited-state non-linear spectroscopy as the technique for the probing of electrons on these metal surfaces. In addition, we briefly describe a new technique probing the surfaces of semiconductors at lOOA-length scale under ambient conditions.
