Advanced Electron Optics for Vibrational Spectroscopy.
Abstract
The objective of this project is to develop an inelastic electron scattering spectrometer with significantly enhanced capabilities for studying physical and chemical phenomena at surfaces. The instrument combines off-the-shelf commercial instrumentation for sample preparation and characterization with a prototype state-of-the-art high resolution electron energy loss spectrometer (EELS) for studying vibrational properties of surfaces. The capabilities of this new instrument are unique. It extends the application of high resolution electron energy loss spectroscopy to include studies of technical surfaces such as polycrystalline surfaces, disordered thin films and non-single crystal alloy surfaces. Important applications are anticipated including studies of technical surfaces as alloys of aluminum and titanium. The new instrument also extends the range of vibrational spectroscopy studies of single crystals. Detailed tests of scattering selection rules and accurate measurements of the energy and angular dependence of inelastic electron scattering are now possible using the new instrument.
