SECONDARY-ELECTRON EMISSION DUE TO BELOW-SURFACE INTERACTION OF AUGERELECTRONS

Elastic and inelastic interaction processes of Anger electrons within st solid are simulated by using the direct Monte Carlo model in order to understand the effect of slow secondary-electron cascade on the Aug er electron emission. Calculated results show considerable importance of the electron cascade for the energy distribution of electrons emitt ed from the surface as well as the total electron yield The energy dis tribution broadens towards the low-energy side due to the emission of slow cascade electrons. However, the question whether the total electr on yield increases or not is strongly dependent on projectile ion spec ies and energy.
