Plasmon-assisted electron-electron collisions at metallic surfaces

Konstantin A. Kouzakov, Jamal Berakdar

摘要:

本文从理论上讨论了一个快的初级电子撞击金属表面引起的次级电子的射出,并假设入射电子与金属中的电子直接散射,计算了Al和Be表面的电子对能量分布。不同的模型筛选的电子-电子相互作用的检查和足迹的表面和体等离子体激元模式进行了确定和分析。制定的理论方法进行了比较与现有的实验数据的电子对发射从铝。

英文摘要:

We present a theoretical treatment for the ejection of a secondary electron from a clean metallic surface induced by the impact of a fast primary electron. Assuming a direct scattering between the incident, primary electron and the electron in a metal, we calculate the electron-pair energy distributions at the surfaces of Al and Be. Different models for the screening of the electron-electron interaction are examined and the footprints of the surface and the bulk plasmon modes are determined and analyzed. The formulated theoretical approach is compared with the available experimental data on the electron-pair emission from Al.
