    • Electrochemically driven degradation of chemical solution deposited ferroelectric thin-films in humid ambient 

      Dahl-Hansen, Runar Plunnecke; Polfus, Jonathan Marc; Vøllestad, Einar; Akkopru-Akgun, Betul; Denis, Lyndsey; Coleman, Kathleen; Tyholdt, Frode; Trolier-Mckinstry, Susan E; Tybell, Per Thomas Martin (Peer reviewed; Journal article, 2020)
      The ambient humidity significantly accelerates the degradation of lead zirconate titanate (PZT) films in microelectromechanical systems; the cause of such degradation is under debate. Here, it is shown that the degradation ...

    • Low-energy properties of electrons and holes in CuFeS2 

      Brekke, Bjørnulf; Malyshev, Roman; Svenum, Ingeborg-Helene; Selbach, Sverre Magnus; Tybell, Per Thomas Martin; Brüne, Christoph; Brataas, Arne (Peer reviewed; Journal article, 2022)
      The antiferromagnetic semiconductor CuFeS2 belongs to a magnetic symmetry class that is of interest for spintronics applications. In addition, its crystal lattice is compatible with Si, making it possible to integrate it ...

    • Magnetic domain configuration of (111)-oriented LaFeO3 epitaxial thin films 

      Hallsteinsen, Ingrid; Moreau, Magnus; Chopdekar, R.V.; Christiansen, Emil; Nord, Magnus Kristofer; Vullum, Per Erik; Grepstad, Jostein; Holmestad, Randi; Selbach, Sverre Magnus; Scholl, A; Arenholz, E; Folven, Erik; Tybell, Per Thomas Martin (Peer reviewed; Journal article, 2017)
      In antiferromagnetic spintronics control of the domains and corresponding spin axis orientation is crucial for devices. Here we investigate the antiferromagnetic axis in (111)-oriented LaFeO3/SrTiO3, which is coupled to ...

    • Performance and reliability of PZT-based piezoelectric micromirrors operated in realistic environments 

      Dahl-Hansen, Runar Plunnecke; Tyholdt, Frode; Tybell, Per Thomas Martin (Chapter, 2018)
      The number of application areas for piezoelectric micro electromechanical systems based on PZT have increased rapidly over the years. Thus, to continue the development towards commercial deployment, characterizing lifetime ...

    • Structural investigation of epitaxial LaFeO_3 thin films on (111) oriented SrTiO_3 by transmission electron microscopy 

      Christiansen, Emil; Nord, Magnus Kristofer; Hallsteinsen, Ingrid; Vullum, Per Erik; Tybell, Per Thomas Martin; Holmestad, Randi (Peer reviewed; Journal article, 2015)
      We report on structural domains in LaFeO3 epitaxial thin films on (111) oriented SrTiO3 observed by transmission electron microscopy using low magnification dark field imaging and high resolution transmission electron ...
