Silver vapor supersonic jets: expansion dynamics, cluster formation, and film deposition
Original language description
Supersonic jets of metal vapors with carrier gas are promising for producing nanostructured metal films at relatively low source temperatures and high deposition rates.Effects of the carrier gas on the jet composition and expansion dynamics,as well as on film properties,remain virtually unexplored.In this work,the free-jet expansion of a mixture of silver vapor with helium in a rarefied regime at an initial temperature of 1373 K is investigated through mass spectrometry and direct-simulation Monte Carlo methods.Introducing the carrier gas into the source is found to result in a transition from a collisionless to a collision-dominated expansion regime and dramatic changes in the Ag jet,which becomes denser,faster,and more forward-directed.The changes are shown to be favorable for the formation of small Ag clusters and film deposition.At a fairly high helium flow,silver Ag2 dimers are observed in the jet,both in the experiment and the simulations,with a mole fraction reaching 0.1%.
