Nanostructuring

Energetic ions, depending on their mass and energy, have different roles in materials science. The experiments in the field of nanomaterials, exploiting the special features of ion beams were initiated at IUAC about five years back. The areas of research and investigations of ion beams in nananostructuring are (i) synthesis of nanostructures and (ii) study of the modifications of existing buried nanoparticles in a matrix so as to explore the possibility of engineering the size and shape of the nanostructures. IUAC has the facilities to provide (i) 1-1.5 keV wide beam (2 inch diameter), (ii) typically ~100 keV to 1 MeV ions of C, N, O, Ar, Kr etc. and (iii) swift heavy ions (energies from 50 MeV to 200 MeV of Li, C, Si, Ni, Ag, Au, etc). All these have been effectively used for themes stated above and noteworthy results have been obtained in synthesis of different nanocomposites (metal-silica, metal-polymers, metal-ZnO etc.), ripples at surface and engineering the size and shape of particles embedded in silica matrix. Some activities are initiated on possible applications as well as theoretical simulations.
