Plasmon Energy Losses of Electrons in Multilayer Dielectric Structures
The possibilities of engineering energy losses, created in the cascade process of electron-electron scattering during the interaction of multilayer dielectric structures with ionizing radiation, are considered. It is shown that the contribution of surface plasmons associated with layer boundaries to electron energy losses is significant only for nanometer layer thicknesses and increases with increasing electron energy. At the same time, surface states associated with longitudinal optical phonons in ionic crystals significantly change energy losses during electron thermalization and can lead to an increase in the efficiency and rise rate of scintillation in nanostructured systems.
