Hello everyone,
the purpose of my question is to find out the way to separate AUGER from secondary electrons. I think? i know the way that each of them is produced but i cannot figure out how can we separate them since both come out of the surface of our material in a SEM let's say experiment. What i think i have understood correctly, is that in a SEM experiment, the secondary electrons come out of the outer in most cases orbitals either by 1) inelastic scattering with the incident beam or 2) in most cases ( 10 times more likely to happen than the 1 case that i just described) by the backscatterd electrons which in their way out of the material ( since the bse electrons tend to go deeper in the material ) excite those outer electrons, which if I am not wrong is the reason why we find most of the secondary electrons at the same place (angle) that we find the bse elctrons. The definition of the AUGER electrons is pretty much everywhere the same and pretty clear i think. And finally why in ELECTRON YIELD vs ELECTRON ENERGY graphs secondary electrons have lower energy than auger electrons? Thanks for your time
