    • Charged Particle Lithography for the Fabrication of Nanostructured Optical Elements 

      Flatabø, Ranveig (Doctoral thesis, 2018-08-31)
      This thesis work focuses on nanostructured optical elements for light and matter waves that have been fabricated using helium ion beam lithography and electron beam lithography. The motivation of this thesis has been to ...

    • Experimental and theoretical investigation of waveguided plasmonic surface lattice resonances 

      Ugulen, Håvard Stavn; Flatabø, Ranveig; Sultan, Mansoor A.; Hastings, Jeffrey T.; Greve, Martin Møller (Journal article; Peer reviewed, 2022)
      Plasmonic nanostructures are good candidates for refractive index sensing applications through the surface plasmon resonance due to their strong dependence on the surrounding dielectric media. However, typically low ...

    • Fast resolution change in neutral helium atom microscopy 

      Flatabø, Ranveig; Eder, Sabrina Daniela; Ravn, Anders K; Samelin, Bjørn; Greve, Martin Møller; Reisinger, Thomas; Holst, Bodil (Peer reviewed; Journal article, 2018)
      In neutral helium atom microscopy, a beam of atoms is scanned across a surface. Though still in its infancy, neutral helium microscopy has seen a rapid development over the last few years. The inertness and low energy of ...

    • Graphene and graphene oxide on Ir(111) are transparent to wetting but not to icing 

      Kyrkjebø, Signe; Cassidy, Andrew; Akhtar, Naureen; Balog, Richard; Scheffler, Martha; Hornekær, Liv; Holst, Bodil; Flatabø, Ranveig (Journal article; Peer reviewed, 2021)
      Anti-icing coatings reduce the freezing onset temperature for water by changing the chemical and physical environment at the water-substrate interface to prevent ice nucleation and growth. Graphene oxide has several ...

    • Light absorption and scattering of 40–170 nm gold nanoparticles on glass substrates 

      Flatabø, Ranveig; Holm, Vårin Renate Andvik; Eidsvåg, Håkon; Holst, Bodil; Greve, Martin Møller (Peer reviewed; Journal article, 2017)
      The localized surface plasmon resonance (LSPR) effect in metal nanoparticles is important for many applications ranging from detectors and sensors to photovoltaic devices. The LSPR wavelength is sensitive to the shape, ...

    • Optical Properties of Metal Nanoparticle Arrays Created using Electron Beam Lithography for Solar Cell Application 

      Flatabø, Ranveig (Master thesis, 2014-06-02)
      Metal nanoparticles (MNPs) are of key interest in many research fields due to their unique optical properties, which are largely dominated by the localized surface plasmon resonance (LSPR) effect. The LSPR effect gives ...
