    • Aging effects on the nucleation of Pb nanoparticles in silica 

      Luce, Flavia Piegas; Kremer, Felipe; Reboh, Shay; Fabrim, Zacarias Eduardo; Sanchez, Dario Ferreira; Zawislak, Fernando Claudio; Fichtner, Paulo Fernando Papaleo (2011) [Artigo de periódico]
      The ion beam synthesis of Pb nanoparticles (NPs) in silica is studied in terms of a two step thermal annealing process consisting of a low temperature long time aging treatment followed by a high temperature short time ...

    • Formation of Ge nanoparticles in SiOxNy by ion implantation and thermal annealing 

      Mirzaei, Sahar; Kremer, Felipe; Sprouster, David J.; Araújo, Leandro Langie; Feng, Ruixing; Glover, C. J.; Ridgway, M.C. (2015) [Artigo de periódico]
      Germanium nanoparticles embedded within dielectric matrices hold much promise for applications in optoelectronic and electronic devices. Here we investigate the formation of Ge nanoparticles in amorphous SiO1.67N0.14 as a ...

    • Lift-off protocols for thin films for use in EXAFS experiments 

      Decoster, S.; Glover, C. J.; Johannessen, B.; Giulian, Raquel; Sprouster, David J.; Kluth, Patrick; Araújo, Leandro Langie; Hussain, Zohair S.; Schnohr, Claudia S.; Salama, H.; Kremer, Felipe; Temst, Kristiaan; Vantomme, A.; Ridgway, M.C. (2013) [Artigo de periódico]
      Lift-off protocols for thin films for improved extended X-ray absorption fine structure (EXAFS) measurements are presented. Using wet chemical etching of the substrate or the interlayer between the thin film and the ...

    • Low temperature aging effects on the formation of Sn nanoclusters in SiO/sub 2/Si films and interfaces 

      Kremer, Felipe; Lopes, João Marcelo Jordão; Zawislak, Fernando Claudio; Fichtner, Paulo Fernando Papaleo (2007) [Artigo de periódico]
      The formation of Sn nanocrystals NCs in ion implanted SiO2 /Si films is investigated using Rutherford backscattering spectrometry and transmission electron microscopy. Low temperature and long time aging treatments followed ...
