Inelastic Scattering Cross Section of Si Determined from Angular Dependent Reflection Electron Energy Loss Spectra

Determining the band gap and mean kinetic energy of atoms from reflection electron energy loss spectra.

Reflection electron energy loss spectra from some insulating materials (CaCO3, Li2CO3, and SiO2) taken at relatively high incoming electron energies (5-40 keV) are analyzed. Here, one is bulk sensitive and a well-defined onset of inelastic excitations is observed from which one can infer the value of the band gap. An estimate of the band gap was obtained by fitting the spectra with a procedure ...

Extracting the Ag surface and volume loss functions from reflection electron energy loss spectra

Reflection electron energy loss spectra have been measured for silver using incoming electrons with energies between 5 and 40 keV, in a surface and volume-sensitive geometry. Bulk and surface loss functions are extracted from these data and various consistency checks are applied to the obtained loss functions. Depositing minute amounts of Al onto the Ag surface causes a severe reduction in surf...

Electron Scattering from Disilane (si 2 H 6 ) Molecules. Absolute Total Cross Section Measurements from 1 to 370 Ev Electron Scattering from Disilane (si 2 H 6 ) Molecules. Absolute Total Cross Section Measurements from 1 to 370 Ev

Absolute grand total cross sections (TCSs) for electron–disilane (Si2H6) scattering have been measured over the energy range from 1 to 370 eV in a linear transmission experiment. The low-energy TCS is dominated by a broad resonant-like enhancement. In the region of the maximum the present grand TCS values appeared to be distinctly lower than previously reported integral elastic cross section da...

Electron scattering from Xe: the relation between the differential elastic cross section and shape and intensity of the energy loss spectra

The measurement of the energy loss spectra of energetic electrons scattered from Xe over large angles is reported. The incoming energy was chosen between 600 eV and 1550 eV. The calculated Xe elastic scattering cross section has a sharp minimum for 750 eV electrons near 135◦. This minimum is confirmed by studying a Xe–H2 mixture and separating their elastic peak based on the recoil effect. The ...
