    • Design and fabrication of nanostructures for enhaced light absorption in silicon 

      Domínguez Fernández, Sagrario (2015)   Tesis doctoral / Doktoretza tesia  OpenAccess
      Nanostructures are being widely studied in the scientific community for many different applications because they present novel properties different from those observed in matter at the macroscale. For example, electromagnetic ...
    • Simple fabrication of ultrahigh aspect ratio nanostructures for enhanced antireflectivity 

      Domínguez Fernández, Sagrario; Cornago Santos, Ignacio; Bravo Larrea, Javier Upna; Pérez Conde, Jesús Upna; Choi, Hyungryul J.; Kim, Jeong-Gil; Barbastathis, George (American Vacuum Society, 2014)   Artículo / Artikulua  OpenAccess
      In this work, the authors present a novel fabrication process to create periodic nanostructures with aspect ratio as high as 9.6. These nanostructures reduce spectral reflectance of silicon to less than 4% over the broad ...
    • Strong angular dependence of resonant states in 2D dielectric cylinder rings 

      Andueza Unanua, Ángel María; Pérez Conde, Jesús Upna; Sevilla Moróder, Joaquín Upna (AIP Publishing, 2018)   Artículo / Artikulua  OpenAccess
      We investigate collective resonators made of dielectric cylinders assembled as two-dimensional regular octagons and decagons. These structures exhibit collective resonance states that change their intensity with the incident ...
