    • Anisotropic effective medium properties from interacting Ag nanoparticles in silicon dioxide 

      Menegotto, Thiago; Horowitz, Flavio (2014) [Artigo de periódico]
      Films containing a layer of Ag nanoparticles embedded in silicon dioxide were produced by RF magnetron sputtering. Optical transmittance measurements at several angles of incidence (from normal to 75°) revealed two surface ...

    • Optical and structural properties of Si nanocrystals produced by Si hot implantation 

      Sias, Uilson Schwantz; Behar, Moni; Boudinov, Henri Ivanov; Moreira, Eduardo Ceretta (2007) [Artigo de periódico]
      It was already demonstrated that Si hot implantation followed by high-temperature annealing induces the formation of Si nanocrystals Si NCs which when excited in a linear excitation regime present two photoluminescence PL ...

    • Optical properties of Peaked Spectrum radio sources 

      Nascimento, Raquel Santiago; Rodriguez-Ardila, Alberto; Hahn, Luis Gabriel Dahmer; Faria, Marcos Antonio Fonseca; Riffel, Rogério; Oliveira, Murilo Marinello Assis de; Beuchert, Tobias; Callingham, Joseph (2022) [Artigo de periódico]
      In this work, we study the optical properties of compact radio sources selected from the literature in order to determine the impact of the radio-jet in their circumnuclear environment. Our sample includes 58 Compact Steep ...

    • Spin-coating process evolution and reproducibility for power-law fluids 

      Jardim, Pedro Lovato Gomes; Michels, Alexandre Fassini; Horowitz, Flavio (2014) [Artigo de periódico]
      A distinct development of an exact analytical solution for power-law fluids during the spin-coating process is presented for temporal and spatial thickness evolution, after steady state conditions are attained. This solution ...

    • Structural and optical properties of InP quantum dots grown on GaAs(001) 

      Godoy, Marcio P.F. de; Nakaema, Marcelo Kiyoshi Kian; Likawa, Fernando; Brasil, Maria José Santos Pompeu; Lopes, João Marcelo Jordão; Bortoleto, José Roberto Ribeiro; Cotta, Mônica Alonso; Paniago, Rogério Magalhães; Mörschbächer, Marcio José; Fichtner, Paulo Fernando Papaleo (2007) [Artigo de periódico]
      We investigated structural and optical properties of type-II InP/GaAs quantum dots using reflection high energy electron diffraction, transmission electron microscopy, atomic force microscopy, grazing incidence x-ray ...
