Structuring thin films and surfaces by ion beams

Several novel effects caused by the implantation of 5-500 keV heavy ions into thin metallic (multi-)layers, graphite or cl-quartz will be discussed, as investigated by ion-beam analysis, tunneling microscopy and hyperfine methods. In particular, we shall report on recent results of ion-beam induced grain growth and structural and magnetic texturing of metallic films, athermal ion-beam mixing of non-miscible metallic bilayers, ion-induced erosion and defect structures on graphite surfaces, as well as amorphization and epitaxial regrowth of alpha-quartz after ion irradiations.
