Abstract :
Graphite surfaces were irradiated by Ar+ ions at 1 keV with a simultaneous Co supply at room temperature. Various kinds of carbon nanocomposites, such as nanocones with and without nanofibers (NFs) on top, nanorods and bean-like nanoprotrusions, formed depending on Co supply rates. The NFs, ~1.5 ¿m in average length, grew on the top of the nanocones at Co supply rate of 1.0 nm/min, and with increasing the Co supply rate the formation of nanoprotrusions without NFs became prominent. As confirmed by energy-dispersive X-ray analysis, NFs and nanoprotrusions were surely composed of C and Co.
