Temperature effects in the sputtering of a molecular solid by energetic atomic and cluster projectiles

Surf Interface Anal. 2011 Jan;43(1-2):10.1002/sia.3505. doi: 10.1002/sia.3505.

Abstract

Temperature effects in the sputtering of an organic molecule were investigated by subjecting a well defined film of coronene to Au1 and C60 primary ions at 100 and 300 K. Strong field photoionization of the sputtered neutral flux was employed to monitor the change in flight time and kinetic energy distributions of intact and fragmented species.

Keywords: C60 sputtering; molecular solid; organic film; photoionization; temperature effects.
