Vacuum deposition - Wikipedia

Vacuum deposition is a family of processes used to deposit layers of material atom-by-atom or molecule-by-molecule on a solid surface. These processes operate at pressures well below atmospheric pressure (i.e., vacuum).The deposited layers can range from a thickness of one atom up to millimeters, forming freestanding structures.

Is it possible to electroplate from a gallium anode?

Gallium is a difficult metal to deposit without excessive hydrogen generation on the cathode because Ga plating potential is high. Hydrogen generation on the cathode causes the deposition efficiency to be less than because some of the deposition current gets used on forming the hydrogen gas, rather than the Ga film on the substrate or cathode.
