• 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 ...
    • 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 ...
    • 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. ...
