Grazing incidence electron energy loss spectroscopy with primary electrons of a few keV was applied to find the interatomic distance in the outer-most layer of a (111) single crystal surface of vanadium carbide V₆C₅. To compare with this, it was attempted to observe the energy loss spectrum of back-scattered electrons using a higher glancing angle for the same specimen. The atomic distance between vanadium and carbon was found to be 0.174 nm, which is considerably smaller than 0.207 nm, the bulk value. On the other hand, the spectrum of back-scattered electrons gave the distance 0.276 nm, which is much greater than the others. These results are discussed from the theoretical point of view.

Study of different forms of carbon by analytical electron microscopy
1999, Journal of Electron Spectroscopy and Related Phenomena
Polycrystalline diamond films grown on non-scratched Si substrates by the Hot Filament-Chemical Vapor Deposition (HF-CVD) were studied by Parallel EELS (PEELS) and Extended Electron Energy Loss Fine Structure Spectroscopy (EXEELFS) techniques. PEELS spectra of diamond films were compared with those obtained for natural diamond. These spectra show that the plasmon and carbon K-edge main features are almost indistinguishable (in position and shapes) in both, natural and our HF-CVD diamond films. The radial distribution function around the carbon atoms was obtained through the Fourier transform of the extended fine structure located in a 300 eV range beyond the carbon K-edge in the energy loss spectra. The values obtained for the C–C distances are very close (within 0.003 nm) to those of the natural cubic diamond structure. These results were accomplished by analyzing the respective X-Ray diffraction pattern (XRD) of the diamond films. This study confirms the good quality of the diamond films produced by our experimental technique.
Oxygen adsorption on a W(100) surface studied by reflectance spectroscopy and electron energy-loss fine structure
1998, Surface Science
Oxygen adsorption on a W(100) surface has been investigated by means of a multichannel differential reflectance spectroscopy and electron energy-loss fine structure (EELFS). The EELFS above the oxygen K-edge was measured at the exposure of 0.5 ML oxygen. The nearest inter-atomic distance between adsorbed oxygen and tungsten on the top layer was found to be 0.165 nm. This value supports the model that the oxygen is situated on the threefold sites and forms WO₂. Real-time differential reflectance spectroscopy spectra of p-polarized light incident near the Brewster angle in the photon-energy ranging from 1.5 to 5.2 eV were measured during the exposure up to 1.1 ML. The variation of the surface dielectric function for an electric field tangential to the surface reveals that optical transitions around 2.6, 3.9 and 4.7 eV are enhanced below 0.7 ML. The enhanced transitions are related to electronic states originating from adsorbed oxygen at the tungsten surface.
Nitrogen adsorption on a W(100) surface studied by an analysis of electron energy-loss fine structure
1998, Journal of Electron Spectroscopy and Related Phenomena
The influences of annealing and electron bombardment on the adsorption states of nitrogen on a W(100) surface have been investigated by an analysis of electron energy-loss fine structure (EELPS). The nitrogen K-edge EELFS were measured, and converted into radial distribution functions using the Fourier transform to obtain the atomic distance between nitrogen and tungsten. Nitrogen adsorption on a tungsten surface at 400 K induces the formation of a stableβ₂ state, and less stableβ₁ state above 0.5 ML. The nearest-neighbor inter-atomic distance drastically increases from 0.167 nm to 0.187 nm, which corresponds to distance betweenβ₂-nitrogen and tungsten in the second layer, when the surface is exposed at 0.5 ML and annealed at temperatures between 920 K and 1020 K where theβ₁-nitrogen desorbs. The temperature-dependent increase in the atomic distance means that annealing induces a lateral reconstruction of tungsten atoms in the top layer, which is reasonably interpreted with the contracted-domain structure. Bombardment of 2 keV electrons at the dose of 10 A s/cm² on the surface annealed at 770 K after exposing above 0.5 ML at 400 K converts some of theβ₂ state into theβ₁ state, which may result in the decrease in atomic distance between nitrogen and tungsten.
PEELS and EXELFS characterization of diamond films grown by the HF-CVD technique on non-scratched Si substrates
1997, Thin Solid Films
We present a detailed energy loss characterization of natural diamond and diamond films grown on non-scratched Si substrates by the hot-filament chemical vapor deposition technique (with the help of a SiC buffer layer). The energy loss experiments were performed in a transmission electron microscope (TEM) with a GATAN-666 parallel electron energy loss spectrometer (PEELS) attachment. Diamond particles are in the 0.5–1 μm size range as observed by TEM. PEELS spectra show that the plasmon and carbon K-edge main features are very similar (in position and shapes) in both natural and our diamond film. The radial distribution function around the carbon atoms was obtained through the Fourier transform of the extended fine structure located in a 300 eV range beyond the carbon K-edge in the energy loss spectra. The values obtained for the C-C distances are very close (within 0.003 nm) to those of natural cubic diamond structure. These results confirm the good quality of the diamond films produced by our experimental technique.
Identification of different forms of carbon by extended energy loss fine structure
1997, Applied Surface Science
Using extended energy loss fine structure spectroscopy (EXELFS), we obtained the local structure around the carbon atoms in amorphous carbon, highly oriented pyrolytic graphite and a polycrystalline diamond thin film grown by the HF-CVD technique. The experiments were performed in a scanning Auger microprobe in the reflection mode and in a high resolution transmission electron microscope with a PEELS attachment. The values obtained for the local structure applying these techniques, show an error around 12% for EXELFS in the reflection mode and 0.3% for the transmission mode, with respect to their reported crystallographic values. In order not to alter the raw experimental data obtained for the different forms of carbon under the same experimental conditions, the introduction of empirical phase shifts was not applied here. This was done in order to avoid the introduction of empirical phase shifts which are normally used to fit the data to know structural parameters. One of the main objectives of this work is to test the reproducibility of the data when taken in the reflection and in the transmission modes.
Structural surface investigations with low-energy backscattered electrons
1995, Surface Science Reports
The development of electron spectroscopies based on inelastic scattering fine structure is driven mainly by the need for structural methods which allow the investigation of the geometrical environment of different atomic species of the surface region of the sample. The EELFS (Extended Energy Loss Fine Structure) technique, using low-kinetic-energy electrons (1000–2000 eV) in reflection geometry, has been proven a useful tool for local structural investigation of clean surfaces, thin films and chemisorbed species. The main appeal of this technique, besides its experimental accessibility, is that the data analysis follows the procedure used for EXAFS (Extended X-ray Absorption Fine Structure) spectroscopy to obtain the atomic selectivity, the radial distribution function, the coordination number and the thermal and anisotropic effects. The near-edge energy-loss feature has been used to investigate the density of empty states close to E_F and it appeeal particularly sensitive for following the structural changes and for discriminating among various phases and compound formations which occur in the surface region. In this work I review some recent developments, applications and theoretical considerations of the EELFS technique to give local structural parameters and to assess the basic mechanisms which dominate the low-energy electron-surface interaction.
