    Article
    Accés restringit per política de l'editorial
    Hydrogenated silicon thin films were obtained by plasma enhanced chemical vapour deposition under plasma conditions close to the formation of powder. By that means microcrystalline, polymorphous and amorphous silicon layers ...
  • Characterization and application of a-SiCx:H films for the passivation of the c-Si surface 

    Martin Campos, Ignacio Clemente; Vetter, M; Orpella García, Alberto; Puigdollers i González, Joaquim; Voz Sánchez, Cristóbal; Marsal, L F; Pallarès Marzal, Josep; Alcubilla González, Ramón (2002-01)
    Article
    Accés restringit per política de l'editorial
    In this work we investigate the effects of typical thermal treatments on c-Si surface passivation by intrinsic a-SiCx:H films. First, a forming gas anneal (FGA), (400 °C, 30 min in H2/N2) is applied resulting in an improvement ...
  • Analysis of the optimum gain of a high-pass l-matching network for rectennas
