Range of electron penetration


The dielectric function contains contributions from both valence and core electrons. Were these topics helpful? A 36, NS , Since the surface sensitivity is determined by the depth perpendicular to the surface from which electrons can escape, it is best defined using the mean escape depth MED , which is related to the IMFP by. This is because of backscatter that occurs in the material, thus reducing the number of electrons penetrating the material. To read this item, please Download PDF.

Radiation Research

K Kanaya and S Okayama. Proceedings of the National Academy of Sciences List of Issues Current Issue Category: The chance of the radiation hitting an atom or just passing through is the ratio of the area of the atoms over the area of the slab. For low- Z materials, such as organic insulators, scattering from the valence electrons is the major loss mechanism for incident electron energies from 10 eV to 10 keV. Academic Press, San Diego, The curve follows an exponential very well.

Penetration and energy-loss theory of electrons in solid targets - IOPscience

Since the surface sensitivity is determined by the depth perpendicular to the surface from which electrons can escape, it is best defined using the mean escape depth MED , which is related to the IMFP by. As for subexcitation electrons, the new electron scattering cross sections of Michaud et al. To find out more, see our Privacy and Cookies policy. However they are loosing it in a slightly different way, and the rate that they loose energy is roughly inversely proportional to the amount of energy that they have.
