Abstract
Scanning tunneling microscopy (STM) and atomic force microscopy (AFM) were used to investigate the surface of highly oriented pyrolytic graphite (HOPG ) irradiated with 209 MeV Kr or 830 MeV U ions, The density of hillocks fou nd on samples irradiated by Kr and U ions indicates synergism of electronic and nuclear stopping processes. Carbon nanotubes (CNTs) were found on all of the investigated samples, STM images show an atomic arrangement identica l with that of graphite. AFM revealed sputtering craters from which emerge CNTs, the vibration of some CNTs was observed. (C) 1999 Elsevier Science B. V. All rights reserved.
