    We report the experimental characterization of two-dimensional (2D) macroporous silicon photonic crystals using angular-dependent reflectance spectroscopy in the mid-IR region. We have investigated different sample structures ...
  • Investigation of the formation of silicon nanocrystals by annealing of amorphous SiCx/c-Si structures 

    Torres, I; Vetter, M; Ferré Burrull, José; Marsal, L F; Orpella García, Alberto; Alcubilla González, Ramón; Pallarès Marzal, Josep (2007-04)

    In this work, we study the changes in the optical properties of 300-nm-thick hydrogenated amorphous silicon carbide layers after an annealing process. Both intrinsic and phosphorus-doped amorphous silicon carbide layers ...
  • Mid-IR characterization of photonic bands in 2D photonic crystals on silicon 

    Kral, Z; Ferré Burrull, José; Todorov Trifonov, Trifon; Marsal, Lf; Rodríguez Martínez, Ángel; Pallares, J; Alcubilla González, Ramón (2008-09-30)
    Article

    We report the characterization of two-dimensional silicon photonic crystals using angular-dependent reflectivity in the mid-IR. The photonic crystals are obtained by electrochemical etching of an ordered array of holes ...
  • Polymer microfibers obtained using porous silicon templates 

    Marsal Garví, Lluís Francesc; Formentín, P.; Palacios, R.; Todorov Trifonov, Trifon; Ferré Burrull, José; Rodríguez Martínez, Ángel; Pallarès Marzal, Josep; Alcubilla González, Ramón (2008)
