Atomically resolved scanning tunnelling microscopic images were obtained of the nanostructures on various types of surface bombarded with highly charged ions. In the scanning tunnelling microscopic image of a highly oriented pyrolytic graphite surface (29Xe+-impact), a protrusion structure was observed with √3 x √3 R30° surface reconstruction around the impact site. A crater-like structure was formed on a Si(111)-(7 x 7) surface by an 50I+ highly charged ion impact. An atomic image ~0.1nm in height was also observed around the missing top-most layers of the crater.
