      Dahl-Hansen, Runar Plünnecke (Doctoral theses at NTNU;2020:125, Doctoral thesis, 2020)
      Since its discovery, silicon-based microelectromechanical systems (MEMS) have had a significant impact on the technological development of sensors and actuators. Using piezoelectric materials deposited as thin-films on a ...

    • Structural and chemical stability of the hexagonal manganites 

      Skjærvø, Sandra Helen (Doctoral theses at NTNU;2017:252, Doctoral thesis, 2017)
      The link between atomic interactions and functional properties in the fascinating material system called hexagonal manganites is investigated in this thesis. By using both neutron scattering measurements and first principles ...

    • Syntese av komplekse oksider med pulset laser deponering 

      Lauvmo, Stig (Master thesis, 2006)
      Norges første pulset laser deponerings (PLD) lab ble påbegynt høsten 2005 av NTNU i samarbeid med Sintef og ble ferdigstilt våren 2006. Pulset laser deponering brukes til deponering av komplekse oksider som SrRuO3(SRO) og ...

    • Synthesis and characterization of (111)- oriented perovskite oxide heterostrctures 

      Bolstad, Torstein (Doctoral theses at NTNU;2019:14, Doctoral thesis, 2019)
      The limits of silicon in semiconductor devices are fast approaching, with feature sizes reaching the realm where quantum effects start to dominate. A promising approach is to include materials with new functionality such ...

    • Synthesis and Characterization of multiferroic epitaxial Perovskite Oxide thin Film Heterostructures - Implications of [111] epitaxy of STO, BTO and LSMO 

      Engh, Matthias Michael (Master thesis, 2014)
      A surge of research on perovskite oxide heterostructures has been excited by the invention of deposition techniques, such as pulsed laser deposition and the need for novel solutions in order to sustain Moores rate for ...

    • Synthesis of ferroelectric nanostructures 

      Rørvik, Per Martin (Doktoravhandlinger ved NTNU, 1503-8181; 2008:321, Doctoral thesis, 2008)
       The increasing miniaturization of electric and mechanical components makes the synthesis and assembly of nanoscale structures an important step in modern technology. Functional materials, such as the ferroelectric ...

    • Techniques for structuring Lead-Lanthanum-Zirconium-Titanium 

      Smievoll, Silje (Master thesis, 2006)
      This thesis describes different approaches for etching of Lead Lanthanum Zirconate Titanate, PLZT, and Lead Zirconate Titanate, PZT. PZT and PLZT are ceramic ferroelectric materials. They are used in applications ranging ...

    • Toward Growth Control of (111)-oriented Perovskite Thin Films: La0.7Sr0.3MnO3/SrTiO3(111) a model study 

      Hallsteinsen, Ingrid Gullikstad (Master thesis, 2012)
      Control of growth and surface morphology of perovskite oxide thin films is essential for future electronic devices based on such materials. Uncommon crystallographic orientations, like (111), are particularly interesting ...
