  • Controlling the Electrical Properties of Reactively Sputtered High Entropy Alloy CrFeNiCoCu Films 
    Mayandi, Jeyanthinath; Finstad, Terje Gunnar; Stange, Marit Synnøve Sæverud; Vasquez, Geraldo Cristian; Sunding, Martin Fleissner; Løvvik, Ole Martin; Diplas, Spyridon; Almeida Carvalho, Patricia (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Oxide-containing films were made by reactively sputtering a high-entropy alloy target of CrFeCoNiCu. We report on a wide range of changes to the electrical properties made by different heat treatments in oxidizing and ...
  • High entropy alloy CrFeNiCoCu sputter deposited films: Structure, electrical properties, and oxidation 
    Mayandi, Jeyanthinath; Schrade, Matthias; Vajeeston, Ponniah; Stange, Marit Synnøve Sæverud; Lind, Anna Maria; Sunding, Martin Fleissner; Deuermeier, Jonas; Fortunato, Elvira; Løvvik, Ole Martin; Ulyashin, Alexander; Diplas, Spyridon; Almeida Carvalho, Patricia; Finstad, Terje Gunnar (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)
    High entropy alloy (HEA) films of CrFeCoNiCu were deposited by sputtering. Their structure was characterized and their electric transport properties were studied by temperature-dependent Hall and Seebeck measurements. The ...
  • Increasing the thermal expansion of proton conducting Y-doped BaZrO3 by Sr and Ce substitution 
    Dayaghi, Amir Masoud; Haugsrud, Reidar; Stange, Marit Synnøve Sæverud; Larring, Yngve; Strandbakke, Ragnar; Norby, Truls Eivind (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Proton conducting oxide electrolytes find potential application in proton ceramic fuel cells and electrolyzers operating at intermediate temperatures, e.g. 400–600 °C. However, state-of-the-art proton conducting ceramics ...
  • Layered microstructures based on BaZr0.85Y0.15O3−δ by pulsed laser deposition for metal-supported proton ceramic electrolyser cells 
    Stefan, Elena; Stange, Marit Synnøve Sæverud; Denonville, Christelle; Larring, Yngve; Hildenbrand, Nicolas; Norby, Truls Eivind; Haugsrud, Reidar (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Planar metal-supported cell designs provide cost-effective scaling-up of solid oxide fuel cells and electrolysers. Here, we report on the fabrication of a BaZr0.85Y0.15O3−δ–NiO (BZY15–NiO) composite electrode and ...
  • 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 (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 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 ...
