• Evolution of SiOx shell layers on SiC-SiOx core-shell nanowires 

      Broggi, Andrea; Ringdalen, Eli; Tangstad, Merete (Peer reviewed; Journal article, 2020)
      Composite core-shell SiC-SiOx nanowires can be produced by heating quartz and SiC powders, with addition of Ar(g) or He(g). The two powders are mixed to create pellets, which will react to SiO(g) and CO(g) at elevated ...
    • Selective etching of nanostructured a-Si:Al and its effect on porosity, Al gradient and surface oxidation 

      Kjeldstad, Torunn; Thøgersen, Annett; Stange, Marit Synnøve Sæverud; Jensen, Ingvild Julie Thue; Nilsen, Ola; Galeckas, Augustinas; Monakhov, Eduard (Peer reviewed; Journal article, 2020)
      Nanoporous amorphous silicon (a-Si) with <5 nm cylindrical pores have been fabricated by phase separation of aluminum (Al) and silicon, forming self-assembled Al nanowires (NWs), followed by subsequent removal of Al by wet ...
    • Surface effects and optical properties of self-assembled nanostructured a-Si:Al 

      Kjeldstad, Torunn; Thøgersen, Annett; Stange, Marit Synnøve Sæverud; Jensen, Ingvild Julie Thue; Monakhov, Eduard; Galeckas, Augustinas (Journal article; Peer reviewed, 2019)
      We present a study of the surface effects and optical properties of the self-assembled nanostructures comprised of vertically aligned 5 nm-diameter Al nanowires embedded in an amorphous Si matrix (a-Si:Al). The controlled ...
