    Photonic Crystals (PhC) are structured materials, which show very attractive optical properties. In this report, we study and discuss the reflection and emission characteristics of a “black face” Macro-porous Silicon (MpSi) ...
  • Catalytic membrane reactors based on macroporous silicon for hydrogen production 

    Vega Bru, Didac; Hernández Díaz, David; López, E.; Jiménez, Nuria; Todorov Trifonov, Trifon; Rodríguez Martínez, Ángel; Alcubilla González, Ramón; Llorca Piqué, Jordi (2010)
    Conference report
    Open Access
    The typology of using hydrogen as an energy carrier and its implementation in portable fuel cells has motivated a considerable research interest in the development of new efficient hydrogen production technologies. Hydrogen ...
  • Macroporous silicon : a next generation catalytic monolith for ethanol steam reforming 

    Vega Bru, Didac; Hernández Díaz, David; Todorov Trifonov, Trifon; Rodríguez Martínez, Ángel; Alcubilla González, Ramón; López, E.; Jiménez, Nuria; Llorca Piqué, Jordi (Publicacions de la Universitat de València (PUV), 2011)
    Conference report

    Macroporous silicon membranes, consisting of straight parallel pores with a diameter of 3.3μm and depth/width ratio >60, are used as microreactors for high efficiency hydrogen generation via steam reforming of ethanol. The ...
  • Negative Refraction Index in 3D MAcroporous Silicon Photonic Crystals 

    Vega Bru, Didac; Todorov Trifonov, Trifon; Hernández García, David; Rodríguez Martínez, Ángel; Alcubilla González, Ramón (2011)
    Conference report
    Restricted access - author's decision
    Photonic crystals (PhC) are sturctured materials, which show very attractive propieties, specially their optical behaviour and electromagnetic wave propagation. In this paper, we simulate a three-dimensional Photonic ...
  • Novel Electronic Devices in Macroporous Silicon: Design of FET Transistors for Power Applications 

    Rodríguez Martínez, Ángel; Vega Bru, Didac; Najar, R.; Pina, M. (2011-07)
    Article
    Restricted access - publisher's policy
    In this paper, we study the application of macroporous silicon (MpSi) to the fabrication of transistors: Four different FET transistor structures are proposed using MpSi as the base material. These devices have been studied ...
  • Simulation and analysis of photonic structures in macroporous silicon 

    Vega Bru, Didac (Universitat Politècnica de Catalunya, 2009-07-13)
    Master thesis (pre-Bologna period)
    Open Access
    This Master Thesis is dedicated to photonic crystal, in particular to macroporous silicon. We introduce the concepts of crystallography, and symmetry, and important associated tools to its study, the Reciprocal lattice, ...
  • Tuning the emissivity of 3D macroporous silicon in the mid-infrared 

    Hernández Díaz, David; Vega Bru, Didac; Garin Escriva, Moises; Todorov Trifonov, Trifon; Rodríguez Martínez, Ángel; Alcubilla González, Ramón (2010)
    Conference report
