Angular-Resolved Electron Emission Studies of Microwave Materials.
Abstract
The purpose of our program is to investigate the electronic properties of bulk solids, surfaces of solids, and adsorbed molecules on solid surfaces using the newly-developed method of polarization-dependent angle-resolved ultraviolet photoemission spectroscopy (PARUPS). The program utilizes the unique properties of synchrotron radiation emitted from the Wisconsin storage ring which forms an intense continuum which extends well past 200 eV in energy. The portion of this continuum we have used depends on our monochromator and extends from 6 eV to about 40 eV. It is possible to take data at any selected photon energy in this range, as well as to do so while varying the photon energy continuously. The radiation is linearly polarized so it is possible to study photoemission effects which depend on the orientation of the polarization vector with respect to the crystal axes of the sample. Such data one to draw inferences about the electronic structure, wave function symmetry and, in certain cases, the orientation of adsorbed molecules.
