    • 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 ...

    • A giant reconstruction of α-quartz (0001) interpreted as three domains of nano dauphine twins 

      Eder, Sabrina Daniela; Fladischer, Katrin; Yeandel, S.R.; Lelarge, Anne; Parker, Stephen C.; Søndergård, Elin; Holst, Bodil (Peer reviewed; Journal article, 2015-10-08)
      Silica (SiO2) is one of the most common materials on Earth. The crystalline form α-quartz is the stable silica polymorph at ambient conditions although metastable forms exist. α-quartz is a piezoelectric material, it can ...

    • Image formation in the scanning helium microscope 

      Fahy, Adam; Eder, Sabrina Daniela; Barr, Matt; Martens, Joel; Myles, T.A.; Dastoor, Paul C. (Peer reviewed; Journal article, 2018)
      The scanning helium microscope (SHeM) is a new addition to the array of available microscopies, particularly for delicate materials that may suffer damage under techniques utilising light or charged particles. As with all ...

    • A neutral matter-wave microscope (NEMI): Design and setup 

      Eder, Sabrina Daniela (Doctoral thesis, 2012-03-09)
      Matter wave microscopes such as electron microscopes or helium ion microscopes are vital tools in numerous fields of sciences. This thesis presents the design of a new matter wave microscope using neutral helium atoms as ...

    • Observation of the boson peak in a two-dimensional material 

      Tømterud, Martin; Eder, Sabrina Daniela; Büchner, Christin; Wondraczek, Lothar; Simonsen, Ingve; Schirmacher, Walter; Manson, Joseph R.; Holst, Bodil (Journal article; Peer reviewed, 2023)
      The boson peak is an excess in the phonon vibrational density of states relative to the Debye model. It has been observed in a wide range of amorphous materials, from inorganic glasses to polymers. Two-dimensional random ...

    • Sub-resolution contrast in neutral helium microscopy through facet scattering for quantitative imaging of nanoscale topographies on macroscopic surfaces 

      Eder, Sabrina Daniela; Fahy, Adam; Barr, Matthew G.; Manson, Joseph R.; Holst, Bodil; Dastoor, Paul C. (Journal article; Peer reviewed, 2023)
      Nanoscale thin film coatings and surface treatments are ubiquitous across industry, science, and engineering; imbuing specific functional or mechanical properties (such as corrosion resistance, lubricity, catalytic activity ...

    • Taxonomy through the lens of neutral helium microscopy 

      Myles, Thomas A.; Eder, Sabrina Daniela; Barr, Matthew G.; Fahy, Adam; Martens, Joel; Dastoor, Paul C. (Peer reviewed; Journal article, 2019-02-14)
      The field of taxonomy is critically important for the identification, conservation, and ecology of biological species. Modern taxonomists increasingly need to employ advanced imaging techniques to classify organisms according ...

    • Temperature-Dependent Bending Rigidity of AB-Stacked Bilayer Graphene 

      Eder, Sabrina Daniela; Hellner, Simen Kaasa; Forti, Stiven; Nordbotten, Jan Martin; Manson, Joseph R.; Coletti, Camilla; Holst, Bodil (Journal article; Peer reviewed, 2021)
      The change in bending rigidity with temperature κ(T) for 2D materials is highly debated: theoretical works predict both increase and decrease. Here we present measurements of κ(T), for a 2D material: AB-stacked bilayer ...

    • Variation of bending rigidity with material density: bilayer silica with nanoscale holes 

      Tømterud, Martin; Eder, Sabrina Daniela; Büchner, Christin; Heyde, Markus; Freund, Hans Joachim; Manson, Joseph R.; Holst, Bodil (Journal article; Peer reviewed, 2022)
      Two dimensional (2D) materials are a young class of materials that is foreseen to play an important role as building blocks in a range of applications, e.g. flexible electronics. For such applications, mechanical properties ...

    • Velocity distributions in microskimmer supersonic expansion helium beams: High precision measurements and modeling 

      Eder, Sabrina Daniela; Palau, Adria Salvador; Kaltenbacher, Thomas; Bracco, Gianangelo; Holst, Bodil (Peer reviewed; Journal article, 2018)
      Supersonic molecular beams are used in many applications ranging from spectroscopy and matter wave optics to surface science. The experimental setup typically includes a conically shaped, collimating aperture, the skimmer. ...
