Abstract: Modification of the surface morphologies of titanium oxide nanoparticle thin films under swift heavy ion (SHI) irradiation was investigated using glancing angle X-ray diffractometry and atomic force microscopy. Irradiation at low ion fluences leads to grain fragmentation and a narrowing of the grain size distribution, whereas grain growth with increased average grain size and grain size distribution occur at high fluences. Associated with the change in the grain size and size distribution there occurs topological modifications at different fluences of SHI irradiation. The SHI-induced grain fragmentation, grain growth and modification of surface topography are explained by the thermal spike model of ion-matter interaction. © 2011 Taylor & Francis.
