The role of hydrogen incorporation into amorphous carbon films in the change of...
Bundaleski, Nenad; Adame, Carolina F.; Alves, Eduardo; Barradas, Nuno P.; Cerqueira, M. F.; Deuermeier, Jonas; Delaup, Yorick; Ferraria, Ana M.Over the last few years, there has been increasing interest in the use of amorphous carbon thin films with low secondary electron yield (SEY) to mitigate electron multipacting in particle accelerators and RF devices. Previous works found that the SEY increases with the amount of incorporated hydrogen and correlates with the Tauc gap. In this work, we analyse films produced by magnetron sputtering with different...
Nanocomposite thin films based on Au-Ag nanoparticles embedded in a CuO matrix ...
Proença, Maria Manuela Carvalho; Borges, Joel Nuno Pinto; Rodrigues, Marco S.; Meira, Diana Isabela Faria; Sampaio, Paula; Dias, João P.Nanocomposite thin films, composed of monometallic Au and Ag, and bimetallic AuAg nanoparticles, dispersed in a CuO matrix were prepared, characterised and tested for Localized Surface Plasmon Resonance (LSPR) sensing. The films were deposited by reactive magnetron sputtering, followed by a post-deposition thermal annealing to modify the size and shape of the nanoparticles distribution within the oxide matrix. ...
