  • Control of growth orientation in as-deposited epitaxial iron-rich nickel ferrite spinel 
    Bratvold, Jon E.; Sønsteby, Henrik Hovde; Nilsen, Ola; Fjellvåg, Helmer (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    The authors here report epitaxial growth of the ferrimagnet NixFe3–xO4 (NFO) by atomic layer deposition at low temperatures. Films grow epitaxially at a reactor temperature of 250 °C and require no further postannealing ...
  • A foundation for complex oxide electronics -low temperature perovskite epitaxy 
    Sønsteby, Henrik H.; Skaar, Erik; Fjellvåg, Øystein; Bratvold, Jon E.; Fjellvåg, Helmer; Nilsen, Ola (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    As traditional silicon technology is moving fast towards its fundamental limits, all-oxide electronics is emerging as a challenger offering principally different electronic behavior and switching mechanisms. This technology ...
  • Phase and Orientation Control of NiTiO3 Thin Films 
    Bratvold, Jon E.; Fjellvåg, Helmer; Nilsen, Ola (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Subtle changes in the atomic arrangement of NiTiO3 in the ilmenite structure affects its symmetry and properties. At high temperatures, the cations are randomly distributed throughout the structure, resulting in the corundum ...
  • Surface Forces Apparatus Measurements of Interactions between Rough and Reactive Calcite Surfaces 
    Dziadkowiec, Joanna; Javadi, Shaghayegh; Bratvold, Jon E.; Nilsen, Ola; Røyne, Anja (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    nm-Range forces acting between calcite surfaces in water affect macroscopic properties of carbonate rocks and calcite-based granular materials and are significantly influenced by calcite surface recrystallization. We suggest ...
  • Tynne filmer av nanolaminater i Fe-Ti-O-systemet 
    Bratvold, Jon E. (Master thesis / Masteroppgave, 2009)
    Hovedmålet med denne oppgaven har vært å utforske ALD som en mulighet for å syntetisere lagdelte strukturer av α-Fe2O3 og FeTiO3. I tillegg har et helt nytt system for tilførsel av titantetraisopropoksid (Ti-tip) uten bruk ...
