MONTE-CARLO MODEL FOR THE DEPOSITION OF ELECTRONIC-ENERGY IN SOLID ARGON THIN-FILMS BY KEV ELECTRONS

The motion of keV electrons in a film of solid argon and the depth dis tribution of ionizations and excitations are studied using a Monte Car lo simulation. This method does not only allow for accurate inclusion of individual cross sections but also for easy inclusion of finite siz e effects. We have analyzed the effect of the substrate on electron tr ajectories and found an important enhancement of the number of electro n-hole pairs and excitons produced near the interface by electrons ref lected from heavy substrates.
