Cones topped by filaments with submicron diameters grow on carbon surfaces when they are bombarded with energetic (e.g., 1 keV) argon ions. It is shown that sputter redeposition is an important process by which cone growth occurs. The possible role of hydrogen in poisoning growth sites and increasing the density of cones at higher temperature is discussed. Several experiments are proposed to clarify growth mechanisms.
