Visualisation d'une charge d'or dans un évaporateur thermique par canon à électrons
Observation of gold charge in an electron beam thermal evaporator. The electrons bombard the solid gold, which heats up and becomes liquid. The pressure in the chamber being very low (high vacuum), the liquid gold evaporates. The gold vapour thus formed then condenses on a substrate positioned opposite, forming a thin layer. With this type of equipment, it is possible to achieve an accuracy of a few tenths of a nanometre in terms of the thickness of the thin layer that is deposited.
