Abstract

The simulation calculation and analysis on the electron backscattering for ion barrier films (IBFs) of Al₂O₃ were performed by Monte Carlo methods. Simulation and experimental detection both found that electron backscattering ratio is inversely proportional to the incident electron energy, proportional to the film thickness and density. But if the film is thick enough, the back scattering ratio will not continue to increase, will maintain a relatively stable value. This work provided a theory support for fabricating high performance low-level-light device.
