  • Silicon nanocavities: Optical properties and applications 

    Fenollosa Esteve, Roberto; Shi, Lei; Rodriguez, Isabelle; Garin Escriva, Moises; Meseguer Rico, Francisco Javier (2014)
    Conference report
    Open Access
    Silicon is the key enabling material for advanced technologies in electronics, and photonics. Recently, we have developed silicon nanocavities (SNs) [1,2] with particle size between 300 nm and 3000 nm. Silicon has an ...

  • Impact of the absorption in transmittance and reflectance on macroporous silicon photonic crystals 

    Cardador Maza, David; Vega Bru, Didac; Rodríguez Martínez, Ángel (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    The characteristics of reflection and transmission peaks in the spectra of photonic crystals have been studied theoretically and the results compared to measurements performed in fabricated samples. The aim of this work ...

  • High efficiency interdigitated back-contact c-Si solar cells 

    Calle Martín, Eric; Ortega Villasclaras, Pablo Rafael; López Rodríguez, Gema; Martín García, Isidro; Carrió Díaz, David; Voz Sánchez, Cristóbal; Orpella García, Alberto; Puigdollers i González, Joaquim; Alcubilla González, Ramón (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    In this work we describe a baseline fabrication process of interdigitated-back-contact c-Si(p) solar cells, which combines conventional diffusion oven stages to define base p+ and emitter n+ regions at the backside, with ...
  • Effect of nanofluid conductivity and humidity on the self-assembly of nanoparticles deposited by electrospray 

    Coll Valentí, Arnau; Bermejo, Sandra; Martín García, Isidro; Castañer Muñoz, Luis María (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    Electrospray technique has been used in previous works as an excellent way to develop ordered nanostructures. This work focuses on the necessary conditions to achieve 3D nano-ordered layers, which are mainly determined by ...

    Silicon nitride (Si 3 N4 ) planar aplica! waveguidcs have been successfully grown by lowpressure chemical vapor dcposition (LPCVD). Silicon p-type wafers with a (100) orientation were used as subst.ratcs, aiiC! t.he Si3 ...
  • Variación de la frecuencia de trabajo en un cristal fotónico basado en silicio macroporoso al variar la longitud del defecto 

    Cardador, D.; Vega Bru, Didac; Rodríguez Martínez, Ángel (2015)
    Conference report
    Open Access
    En este trabajo se ha estudiado la relación existente entre la frecuencia de trabajo de un cristal fotónico con defecto y el tamaño de dicho defecto. Las simulaciones indican una dependencia lineal entre ambas, a la vez ...
