    • EELS and STEM studies of perovskite oxide heterostructures 

      Nord, Magnus (Doctoral theses at NTNU;2016:361, Doctoral thesis, 2016)
      Perovskite oxide heterostructures have attracted much research interest due to a strong coupling between the local crystal structure and the functional properties. Of special interest are the interfaces of thin film systems, ...

    • Transmission Electron Microscopy Characterization of Degradation Mechanisms in Lithium-ion Batteries 

      Sepehri, Armand (Master thesis, 2022)
      Litium-ion batterier har fremtredd som en lovende løsning for det økende behovet for bærbare, effektive og billige energilagringsenheter. Grafitt har blitt brukt som anodemateriale i kommersielle litium-ion batterier siden ...

    • Vertical GaN nanocolumns grown on graphene intermediated with a thin AlN buffer layer 

      Liudi Mulyo, Andreas; Rajpalke, Mohana Krishnappa; Kuroe, Haruhiko; Vullum, Per-Erik; Weman, Helge; Fimland, Bjørn-Ove; Kishino, Katsumi (Journal article; Peer reviewed, 2018)
      We report on the self-assembled growth of high-density and vertically-oriented n-doped GaN nanocolumns on graphene by radio-frequency plasma-assisted molecular beam epitaxy. Graphene was transferred to silica glass, which ...
