Energy Losses and Mean Free Paths of Electrons in Silicon Dioxide

Theoretical models and calculations are combined with experimental optical data to determine a model energy-loss function for SiO2. Sum-rule checks and comparisons with experimental information are made to insure overall consistency of the model. The model energy-loss function is employed to calculate electron inelastic mean free paths and stopping powers for electrons with energies ¿ 10 keV in SiO2.
