Abstract / Description:We have recently shown that the impact of individual slow highly charged ions is able to induce
permanent nano-sized hillocks on the surface of a CaF2 single crystal. The experimentally observed threshold of the
projectile ion potential energy necessary for hillock formation could be linked to a solid-liquid phase transition
(nano-melting). In this contribution we report on similar nano-sized surface modifications as a result of the potential
energy of impacting highly charged ions for other surfaces.
