Does anyone know if there are highly conductive metals (or any conductive metals) that are not prone to sputtering. Or any non metalic conductors that don't sputter?
Could you perhaps explain your question more? Why would you want such a metal if you are trying to perform sputtering deposition?rppearso said:Does anyone know if there are highly conductive metals (or any conductive metals) that are not prone to sputtering.

Mapes said:Everything's going to sputter to some degree, but perhaps you're looking for the lowest erosion flux under certain conditions. I would have guessed tungsten as well because of its strong atomic bonds (deducible from its high density and refractory nature), but this chart indicates that titanium has a lower sputter yield. (Sigmund's theory indicates that nuclear stopping power is a factor in addition to atomic binding strength.) Carbon (and graphite would satisfy your conductivity requirement) is lower still.

rppearso said:what about graphene coated silver rod, would the layer of graphene prevent sputter of the silver?
f95toli said:No, graphene is -by definition- one atomic layer thick. Hence, although it might slow things down for a little while it will disappear very, very quickly,.
Again, EVERYTHING sputters; it is only the rates that differ.
Also, how would you coat a silver rod with graphene? It sound like something that would be very hard to do.

Conductive metals are materials that allow electricity or heat to flow through them with little resistance. They are characterized by their high electrical and thermal conductivity.
Sputtering is a process in which atoms from a solid surface are ejected into the surrounding environment due to bombardment by high-energy particles. A metal that is prone to sputtering is one that is easily damaged or eroded by this process.
Some examples of conductive metals that are not prone to sputtering include gold, silver, and copper. These metals have a high resistance to sputtering due to their strong atomic bonds and stable crystal structures.
These types of metals are commonly used as coating materials for sensitive instruments such as electron microscopes. They can also be used in vacuum chambers or other environments where sputtering can occur, to prevent damage to equipment.
While these metals have many advantages, they can be more expensive and difficult to work with compared to other materials. They also have lower sputtering yields, meaning they may not be as effective for certain applications where a higher sputtering rate is desired.
