Analysis of electron energy-loss spectra from electron-beam-damaged amorphous AIF3

摘要: Abstract Expressions for the electron energy-loss probability are obtained electrons travelling parallel to, firstly, one and, secondly, two coaxial cylindrical interfaces between different media. These expressions have been evaluated Al-vacuum confirming that modes behave in manner expected. Experimental spectra presented through holes drilled thin films of amorphous AIF3 (a-A1F3) a scanning transmission microscope. Comparison these with calculated indicates discrepancy shape which is attributed to modification a-A1F3 surrounding hole. The presence 6 eV peak some excitation surface mode on spheres aluminium film.
