Editing Sputtering (section)

==Electronic sputtering== 
The term ''electronic sputtering'' can mean either sputtering induced by energetic electrons (for example in a transmission electron microscope), or sputtering due to very high-energy or highly charged heavy ions that lose energy to the solid, mostly by electronic [[Stopping power (particle radiation)|stopping power]], where the electronic excitations cause sputtering.<ref name=Schenkel1997>{{cite journal| author= T.
