摘要
The present work reports the dependence of electronic sputtering on thickness of fullerene film. The energetic ions of 200 MeV An(15+) are taken from NSC Pelletron at New Delhi and the Tandem accelerator at Munich. On-line elastic recoil detection analysis (ERDA) with DeltaE-E telescope detector is used to determine the electronic sputtering yield. We observed systematic decrease in sputtering yield of carbon with increase in film (C-60/silicon) thickness. (C) 2002 Elsevier Science B.V. All rights reserved.
