Recently, considerable research efforts were devoted to the fabrication of extremely small nanostructures of significant potential in nanophotonics and nanoelectronics applications. Slow highly charged ions (HCI), as a promising nanotechnological tool, were successfully utilized for the creation of surface nanostructures in various solids [1]. Based on both the type of the material and ion beam parameters, nanostructures of different shapes (pits, caldera-like, hillocks) and sizes were obtained [2,3]. Here, we review the research progress on HCI-induced nanostructuring and the used theoretical approaches for understanding the creation mechanisms of the observed surface structures.
