    Functionalization of silicon crystal surface by energetic cluster ion bombardment

  • Original language description

    We report the creation of a functional nanostructure on a Si crystal surface by 200 keV C60++ cluster ion bombardment (CIB). We found that the modified layer produced by CIB includes two sublayers.The top 24-nm-thick sublayer is an agglomeration of 5-nm-sized amorphous Si nanodots (a-Si NDs). The deeper 10-nm-thick sublayer is a transient layer of disordered Si as an interface between the a-Si top sublayer and the bulk Si(100). The top a-Si sublayer and the nc-Si transient layer are formed by the localheating effect and shock wave effect, respectively,induced by the cluster ion impacts. The photoluminescence (PL) spectra revealed an emission line centered at a photon energy of 1.92 eV. The absorption spectra of the modified samples exhibit enhanced light absorption at this photon energy. The parameters of the PL line require ascribing the emission origin to the quantum-confinement-induced optical transitions in the a-Si nanodots.
