Sputtering Animations

There are seven animations linked on this page. Five animations are from the work of Zbigniew Postawa and shows the effect of C₆₀ bombardment of Ag. Two are from Arnaud Delcorte's work of Ar sputtering of polystyrene on Ag. They exhibit high and low action events. Enjoy!

Polystyrene/Ag - High and Low Action

The two trajectories presented below exhibit the diversity of sputtering events. These trajectories come from the work of Arnaud Delcorte (Ref 198 and 206 below) of sputtering of polystyrene tetramers on a metal surface. Below is Figure 2 of Ref 206. The trajectories have been categorized according to ejection yield of molecules and action in the Ag substrate.

Classic Sputtering Animations, aka, The Flicks

The staff at the Faculty Multimedia Center at Penn State have converted our sputtering animations to streaming video that can be viewed on a PC or MAC (sorry no UNIX) with Quicktime. Each animation has been subdivided into segments. Each segment has been made into a high resolution copy appropriate for LAN access. In addition, there is a copy of each segment for DOWNLOAD that also can be used with Quicktime.

	General sequence. LAN DL 8.1Mb		Formation of a dimer that preferentially ejects along one crystallographic direction. LAN DL 3.4Mb
	Formation of a Cu pentamer. LAN DL 13.2Mb		Molecular ejection of benzene by two metal atoms. We now call this cooperative uplifting.LAN DL 16.2Mb
	Molecular and dissociative ejection of CO.LAN DL 8.3Mb		Formation of NiCO.LAN DL 4.3Mb

During the summer of 1992, Roger Webb from the University of Surrey, UK, and Roger Smith from Loughborough University, UK, visited Penn State for two weeks. Along with Eric Dawnkaski they made SPUT92. We published the animation along with an extensive text in the International Video J. of Engineering Research (John Wiley & Sons, Ltd) 3, 63-72 (1993).

	Experimental energy and angular distributions of neutral Rh atoms sputtered in the excited 4F7/2 state vs. the ground 4F9/2 state indicate anomolous excitations probabilities for the low energy excited 4F7/2 Rh atoms. Simulations clearly show that collisions of atoms above the surface are responsible for the anomolous excitation probability. The original animation was made by Dan N. Bernardo. The color coding for the atoms is shown to the left. See the references given below for further details.
