Popis:	It is shown experimentally that the seed metals which can cause cone development on ion bombarded metal targets need not to have a lower sputtering yield as widely believed but rather a higher melting point. By lowering the bombarding ion energy to near sputtering threshold values (less than 100 eV) the growth of genuine single crystal whiskers which point in all directions not related to the direction of ion incidence is observed. It is concluded that (intentional or unintentional) seed cones are the result of an interplay among whisker growth, surface movement of atoms, and the effects of sputtering.
