| Abstract: | A model is proposed to describe the secondary electron emission (SEE) of pure normal metals. The various types of collisions suffered by an electron travelling in the solid are analyzed. The dielectric theory is used to account for the collisions with the jellium, including surface effects in an approximate way. The different damping mechanisms for plasmons are reviewed and their influence on SEE is emphasized. The elastic and ionizing collisions with the ionic cores are described by a randium model. The relative importance of each of the above processes for the SEE of normal metals is discussed. |
