Title: Formation of nanostructures upon laser ablation of a binary Si{sub x}(SiO{sub 2}){sub 1-x} mixture

Abstract

The formation efficiency of fractal nanostructures is studied experimentally depending on the composition of the binary silicon-silica mixture during evaporation by millisecond laser pulse. The influence of percolation on the efficiency of nanostructure formation in a laser plume is discovered. It is found that the efficiency is maximal near the critical densities of atoms in the plasma, which correspond both to the three-dimensional and two-dimensional percolation. The dependences of the effective temperatures of the laser plasma and the intensity of spectral lines on the target composition are presented. (interaction of laser radiation with matter. laser plasma)

  • Al{sub 2}O{sub 3}/SiO{sub x}/Al{sub 2}O{sub 3}/SiO{sub x}/ Horizontal-Ellipsis /Si(100) multilayer nanoperiodic structures (MNS) are studied by X-ray absorption near-edge structure spectroscopy (XANES). Experimental XANES spectroscopy spectra are obtained using synchrotron radiation. The formation of Si nanoclusters in the surface layers of the structures during their high-temperature annealing is observed. The structures featured intense size-dependent photoluminescence in the wavelength region near 800 nm. At the same time, it is shown that the formation of aluminum silicates is possible. The inversion effect of the intensity of the XANES spectra during the interaction of synchrotron radiation with MNSs is revealed.
  • Using magnetron cosputtering of SiO{sub 2}, Ge, and Si targets, Si-based SiO{sub 2}:Ge:Si films were fabricated for exploring the influence of Si target proportion (P{sub Si}) and annealing temperature (Ta) on formation, local structure, and phonon properties of nanocrystalline Si{sub 1-x}Ge{sub x} (nc-Si{sub 1-x}Ge{sub x}). At low P{sub Si} and Ta higher than 800 deg. C, no nc-Si{sub 1-x}Ge{sub x} but a kind of composite nanocrystal consisting of a Ge core, GeSi shell, and amorphous Si outer shell is formed in the SiO{sub 2} matrix. At moderate P{sub Si}, nc-Si{sub 1-x}Ge{sub x} begins to be formed at Ta=800 deg. Cmore » and coexists with nc-Ge at Ta=1100 deg. C. At high P{sub Si}, it was disclosed that both optical phonon frequency and lattice spacing of nc-Si{sub 1-x}Ge{sub x} increase with raising Ta. The possible origin of this phenomenon is discussed by considering three factors, the phonon confinement, strain effect, and composition variation of nc-Si{sub 1-x}Ge{sub x}. This work will be helpful in understanding the growth process of ternary GeSiO films and beneficial to further investigations on optical properties of nc-Ge{sub 1-x}Si{sub x} in the ternary matrix.« less
  • The results of X-ray absorption near-edge structure spectroscopy data obtained with synchrotron radiation for multilayered nanoperiodic Al{sub 2}O{sub 3}/SiO{sub x}/Al{sub 2}O{sub 3}/SiO{sub x}/.../Si(100) structures annealed at temperatures of 500–1100°C are reported. The data show that, upon high-temperature annealing (∼1100°C), the structures are modified. The modification is attributed to the formation of Si nanocrystals in deep layers of the structures. At the same time, the structures exhibit size-dependent high-intensity photoluminescence in the photon-energy range 1.4–1.52 eV.
  • Thin films composed of polycrystalline Er{sub x}Yb{sub 2-x}O{sub 3} grains and crystalline Er{sub x}Yb{sub 2-x}Si{sub 2}O{sub 7} layers were formed on a Si(111) substrate by RF - sputtering and subsequent thermal annealing in Ar gas ambient up to 1100 Degree-Sign C. The films were characterized by synchrotron radiation grazing incidence X-ray diffraction, cross-sectional transmission microscopy, energy dispersive X-ray spectrometry and micro photoluminescence measurements. In the annealed film of 950 Degree-Sign C it is observed that the I{sub 15/2} - I{sub 13/2} Er{sup 3+} photoluminescent transition exhibits simultaneously maximum intensity and peak width at room temperature. This effect satisfies the requirementsmore » for broadening the C-band of an optical amplifier on Si.« less
