Studies of Electron Interactions with Communications Materials.
Abstract
This report summarizes various theoretical and experimental studies designed to yield information on electron interactions with various communications materials. Experimental electron slowing-down spectra have been obtained for Si and for Al2O3 and various theoretical models proposed to account for these spectra. Attempts to measure electron attenuation lengths for photo-excited electrons in carbon, polystyrene, and gold over a range of photon energies from 20 to 64 eV, are described. A critique of photoelectric yield methods for measuring electron attenuation lengths stresses the difficulty of obtaining small values of this quantity to an accuracy of even 10%. Theoretical models combined with experimental data have resulted in tabulations of mean free path, energy loss, energy straggling, range, and range straggling for electrons in Al, Al2O3, Si, SiO2, Ni, Cu, Ag, Au, Ge, and GaAs.
