Interaction of highly charged ions with insulator surfaces

Selected aspects of the interaction of slow, highly charged ions with insulating surfaces are presented: the electron emission from the interaction of highly charged Ne9+Ne9+ ions with thin SiO2SiO2 films and the calorimetric determination of the potential energy retention in these layers. The results are compared to the interaction of highly charged ions with metallic Au and n-type Si(1 0 0) surfaces. In addition, a short overview of the interaction scenario of HCIs with insulating surfaces is given in the context of more applicative aspects of the interaction of HCIs with insulators like potential sputtering and single ion induced surface modifications.
