    • 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 ...
    • Revisión sobre recubrimientos láser de aleaciones de aluminio 

      Pérez Artieda, Miren Gurutze Upna Orcid; Fernández Carrasquilla, Javier Upna (CENIM, 2008)   Artículo / Artikulua  OpenAccess
      En este artículo se presenta un trabajo de revisión bibliográfica, centrado en los procesos de recubrimiento y tratamiento superficial láser realizados en aleaciones de aluminio. Estos procesos láser son técnicas de ...
    • Silicon-based 0.450-0.475 THz series-fed double dielectric resonator on-chip antenna array based on metamaterial properties for integrated-circuits 

      Alibakhshikenari, Mohammad; Virdee, Bal S.; See, Chan H.; Abd-Alhameed, Raed; Falcone Lanas, Francisco Javier Upna Orcid; Limiti, Ernesto (IEEE, 2019)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The antenna array designed to operate over 0.450-0.475 Terahertz comprises two dielectric resonators (DRs) that are stacked vertically on top of each other and placed on the surface of the slot antenna fabricated on a ...
    • Simple fabrication of ultrahigh aspect ratio nanostructures for enhanced antireflectivity 

      Domínguez Fernández, Sagrario; Cornago Santos, Ignacio; Bravo Larrea, Javier Upna Orcid; Pérez Conde, Jesús Upna Orcid; 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 ...
