Surface excitations in surface electron spectroscopies studied by reflection electron energy-loss spectroscopy and elastic peak electron spectroscopy.
Surface excitations, in addition to bulk excitation, undergone by signal electrons in surface electron spectroscopies, such as Auger electron spectroscopy, and X-ray photoelectron spectroscopy, play an important role in the formation of electron spectra. Those inelastic scattering processes not only induce decay in the peak intensity, but also form background appearing in the lower kinetic ener...
متن کاملSurface microanalysis by reflection electron energy-loss spectroscopy.
Several basic physical concepts of applying eq. Ik = I sigma Nxt to surface microanalysis by reflection electron energy-loss spectroscopy (REELS) are clarified. Here Ik and I are the integrated intensities of the core ionization edge and the low loss part, sigma is the scattering cross section of element x with atomic concentration Nx, and t is the specimen thickness. The reflected inelastic el...
متن کاملSurface Studied with Auger Electron Spectroscopy
We present an Auger electron spectroscopy (AES) study of the adsorption of nitric oxide (NO) on a dean Si(100)2 × 1 surface at 300 and 550 K. Accurate measurements reveal wall resolved fine structure at Auger Si L2.3 w transitions at 62 and 83 eV. These peaks can be attributed to Si-O and Si-N bonds. Furthermore, it is argued that the broadening in the SiLi2,~W Auger transition at 83 eV at 300 ...
متن کاملMetal interface formation studied by high-energy reflection energy loss spectroscopy and electron Rutherford backscattering
We demonstrate that high-energy, high-resolution reflection electron energy loss spectroscopy can provide unique insights into interface formation, especially for the case where an extended interface is formed. By changing the geometry and/or electron energy the electronic structure can be probed over a range of thicknesses (from 10s of Å to more than 1000 Å). At the same time one resolves the ...
