  • Aluminum migration and intrinsic defect interaction in single-crystal zinc oxide 
    Johansen, Klaus Magnus H; Vines, Lasse; Bjørheim, Tor Svendsen; Schifano, Ramon; Svensson, Bengt Gunnar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Vacancy-mediated migration of Al in single-crystal zinc oxide (ZnO) is investigated using secondary-ion mass spectrometry (SIMS) combined with hybrid density-functional theory (DFT) calculations. A thin film of Al-doped ...
  • Highly Correlated Hydride Ion Tracer Diffusion in SrTiO3–xHx Oxyhydrides 
    Liu, Xin; Bjørheim, Tor Svendsen; Vines, Lasse; Fjellvåg, Øystein; Granerød, Cecilie Skjold; Prytz, Øystein; Yamamoto, Takafumi; Kageyama, Hiroshi; Norby, Truls Eivind; Haugsrud, Reidar (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    Mixed oxide hydride anion systems constitute a novel class of materials exhibiting intriguing properties such as solid-state hydride ion conduction and fast anion exchange. In this contribution we derive the kinetics of ...
  • Origin of enhanced conductivity in low dose ion irradiated oxides 
    Borgersen, Jon; Karsthof, Robert Michael; Rønning, Vegard; Vines, Lasse; Von Wenckstern, Holger; Grundmann, Marius; Kuznetsov, Andrej Yu.; Johansen, Klaus Magnus Håland (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Significant resistivity variations have previously been observed in oxides subjected to relatively low ion irradiation doses, nominally insufficient to generate the amount of bulk defects needed to explain the phenomena. ...
