Surface nanostructuring by ion-induced localized plasma expansion in zinc oxide
Surface nanostructuring by ion-induced localized plasma expansion in zinc oxide
El-Said, A. S.; Moslem, W. M.; Djebli, M.
Creation of hillock-like nanostructures on the surface of zinc oxide single crystals by irradiation with slow highly charged ions is reported. At constant kinetic energy, the nanostructures were only observed after irradiation with ions of potential energies above a threshold between 19.1 keV and 23.3 keV. The size of the nanostructures increases as a function of potential energy. A plasma expansion approach is used to explain the nanostructures creation. The calculations showed that the surface nanostructures became taller with the increase of ionic temperature. The influence of charged cluster formation and the relevance of their polarity are discussed.
