    • Characterization of ferroelectric domain walls by scanning electron microscopy 

      Hunnestad, Kasper; Roede, Erik Dobloug; Helvoort, Antonius T. J. van; Meier, Dennis Gerhard (Peer reviewed; Journal article, 2020)
      Ferroelectric domain walls are a completely new type of functional interface, which have the potential to revolutionize nanotechnology. In addition to the emergent phenomena at domain walls, they are spatially mobile and ...

    • Confinement-Driven Inverse Domain Scaling in Polycrystalline ErMnO3 

      Schultheiss, Jan; Xue, Fei; Roede, Erik Dobloug; Ånes, Håkon Wiik; Danmo, Frida Hemstad; Selbach, Sverre Magnus; Chen, Long-Qing; Meier, Dennis (Peer reviewed; Journal article, 2022)
      The research on topological phenomena in ferroelectric materials has revolutionized the way people understand polar order. Intriguing examples are polar skyrmions, vortex/anti-vortex structures, and ferroelectric ...

    • Contact-free reversible switching of improper ferroelectric domains by electron and ion irradiation 

      Roede, Erik Dobloug; Mosberg, Aleksander Buseth; Evans, Donald; Bourret, Edith; Yan, Zewu; Van Helvoort, Antonius; Meier, Dennis (Peer reviewed; Journal article, 2021)
      Focused ion beam (FIB) and scanning electron microscopy (SEM) are used to reversibly switch improper ferroelectric domains in the hexagonal manganite ErMnO3. Surface charging is achieved by local ion (positive charging) ...

    • FIB and Functional Ferroics: Structuring and Correlated Microscopy 

      Roede, Erik Dobloug (Doctoral theses at NTNU;2022:156, Doctoral thesis, 2022)
      Norsk sammendrag FIB og funksjonelle ferroiske materialer For å fortsette utviklingen av raskere og mer energieffektiv elektronikk er vi nødt til å utnytte nye fysiske fenomener. I dette arbeidet studeres ferroiske ...

    • FIB lift-out of conducting ferroelectric domain walls in hexagonal manganites 

      Mosberg, Aleksander Buseth; Roede, Erik Dobloug; Evans, Donald; Holstad, Theodor S.; Bourret, Edith; Yan, Zewu; Van Helvoort, Antonius; Meier, Dennis (Journal article; Peer reviewed, 2019)
      A focused ion beam (FIB) methodology is developed to lift out suitable specimens containing charged domain walls in improper ferroelectric ErMnO3. The FIB procedure allows for extracting domain wall sections with well-defined ...

    • FIB/SEM Characterization of Paper Materials 

      Roede, Erik Dobloug (Master thesis, 2016)
      3D microscopy is of interest for structural characterization of paper materials to study the use of cellulose nanofibrils as a paper additive. Focused ion beam (FIB) tomography is a promising microscopy technique for this ...

    • Fluorescent Nanocomposites: Hollow Silica Microspheres with Embedded Carbon Dots 

      Delic, Asmira; Mariussen, Espen; Roede, Erik Dobloug; Krivokapic, Alexander; Erbe, Andreas; Lindgren, Mikael; Benelmekki, Maria; Einarsrud, Mari-Ann (Journal article; Peer reviewed, 2021)
      Intrinsically fluorescent carbon dots may form the basis for a safer and more accurate sensor technology for digital counting in bioanalytical assays. This work presents a simple and inexpensive synthesis method for producing ...

    • Magnetic and geometric control of spin textures in the itinerant kagome magnet Fe3 Sn2 

      Altthaler, Markus; Lysne, Erik Nikolai; Roede, Erik Dobloug; Prodan, Lilian; Tsurkan, Vladimir; Kassem, Mohamed A.; Nakamura, Hiroyuki; Krohns, Stephan; Kézsmárki, István; Meier, Dennis Gerhard (Peer reviewed; Journal article, 2021)
      Magnetic materials with competing magnetocrystalline anisotropy and dipolar energies can develop a wide range of domain patterns, including classical stripe domains, domain branching, and topologically trivial and nontrivial ...

    • Non-Destructive Tomographic Nanoscale Imaging of Ferroelectric Domain Walls 

      He, Jiali; Zahn, Manuel; Ushakov, Ivan; Richarz, Leonie; Ludacka, Ursula; Roede, Erik Dobloug; Yan, Zewu; Bourret, Edith; Kézsmárki, István; Catalan, Gustau; Meier, Dennis (Peer reviewed; Journal article, 2024)
