      A transparent TMPyP/TiO2 composite thin film as an HCl sensitive optochemical gas sensor  [Article]

      Cano, Manuel; Castillero Durán, Pedro; Roales, Javier; Brittle, Stuart; Richardson, Tim; Rodríguez González-Elipe, Agustín; Barranco Quero, Ángel (Elsevier, 2010)
      Tetracationic porphyrin (TMPyP) molecules were incorporated into an optically transparent TiO2 thin film, prepared by Glancing Angle Physical Vapour Deposition (GAPVD), by simple infiltration (at pH 6.4). The preparation ...

      Differences in n-type doping efficiency between Al- and Ga-ZnO films  [Article]

      Gabàs, Mercedes; Landa Cánovas, Ángel; Costa Krämer, José Luis; Agulló Rueda, F.; Rodríguez González-Elipe, Agustín; Díaz Carrasco, P.; Hernández Moro, Jorge; Lorite, Israel; Herrero, Pilar; Castillero Durán, Pedro; Barranco Quero, Ángel; Ramos Barrado, J. Ramón (American Institute of Physics, 2013)
      A careful and wide comparison between Al and Ga as substitutional dopants in the ZnO wurtzite structure is presented. Both cations behave as n-type dopants and their inclusion improves the optical and electrical properties ...
