I have been trying to get my head around Electron-Beam Lithography and have a small issue with what has been said in the linked YT video.
At 11:35 Chris Mack says that
The more energy the electrons have the further they travel (this I understand) and the less backscattering occurs (this I don't understand).
Why does the energy of the electrons influence how much backscattering occurs? Also he mentioned that
'Higher energy for electrons means less interaction with the material.'
Why is that? I have a hard time understanding why higher energies would influence these two things.
Any answers are helpful, also I would be fine with being pointed into the correct direction and research it myself.
