  • Bondevik, Tarjei; Kuwabara, Akihide; Løvvik, Ole Martin (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    A selective sampling procedure is applied to reduce the number of density functional theory calculations needed to find energetically favorable grain boundary structures. The procedure is based on a machine learning algorithm ...
  • Pike, Nicholas; Løvvik, Ole Martin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Predictions of the anisotropic coefficients of thermal expansion are needed to not only compare to experimental measurement, but also as input for macroscopic modeling of devices which operate over a large temperature ...
  • Bondevik, Tarjei; Ness, Heine H.; Bazioti, Kalliopi; Norby, Truls Eivind; Løvvik, Ole Martin; Koch, Christoph T.; Prytz, Øystein (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    We apply inline electron holography to investigate the electrostatic potential across an individual BaZr0.9Y0.1O3 grain boundary. With holography, we measure a grain boundary potential of −1.3 V. Electron energy loss ...
  • Bernal, Fabian Leonardo Martinez; Sottmann, Jonas; Wragg, David; Fjellvåg, Helmer; Fjellvåg, Øystein; Drathen, Christina; Slawinski, Wojciech Andrzej; Løvvik, Ole Martin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    We report on the structural and magnetic properties of the elusive Jahn-Teller active compound NaCrF3, for first time synthesized in large quantities allowing detailed characterization. The crystal structure of NaCrF3 is ...
  • Berland, Kristian; Shulumba, Nina; Hellman, Olle; Persson, Clas; Løvvik, Ole Martin (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    The thermoelectric properties of 54 different group 4 half-Heusler (HH) alloys have been studied from first principles. Electronic transport was studied with density functional theory using hybrid functionals facilitated ...
