The Interaction of UV-Laser Radiation with Metal and Semiconductor Surfaces.
Abstract
The first observations of image states on solid surfaces were reported about ten years ago using inverse photoemission and two-photon photoemission (2PPE), and the initial stages in the nonlinear spectroscopy of image states emphasized the measurement of the binding energies of these states as well as their dispersion relations or effective masses. More recently, work in this area has sought to exploit the relative precision of image-state spectroscopy by using their high-resolution two-photon photoemission spectra as a probe of surface conditions as well as the interfacial physics. Simultaneously with this work, the image-state spectroscopy has been developed into a powerful and unique probe of surface/near-surface electronic structures and electron dynamics, enabling new insights into the physics of nanostructured. ARO Support of this program has enabled us to make significant progress in uncovering the physics of low-dimensional electron systems, utilizing the high-resolution angle-resolved 2PPE. Our progress is reported below in four sections.
