    • Neutral helium atom microscopy 

      Palau, Adria Salvador; Eder, Sabrina Daniela; Bracco, Gianangelo; Holst, Bodil (Journal article; Peer reviewed, 2023)
      Neutral helium atom microscopy, also referred to as scanning helium microscopy and commonly abbreviated SHeM or NAM (neutral atom microscopy), is a novel imaging technique that uses a beam of neutral helium atoms as an ...

    • 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 ...

    • 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 ...
