Material properties particularly suited to be measured with helium scattering: selected examples from 2D materials, van der Waals heterostructures, glassy materials, catalytic substrates, topological insulators and superconducting radio frequency materials
Holst, Bodil; Alexandrowicz, Gil; Avidor, Nadav; Benedek, Giorgio; Bracco, Gianangelo; Ernst, Wolfgang E.; Farias, Daniel; Jardine, Andrew P.; Lefmann, Kim; Manson, Joseph R.; Marquardt, Roberto; Artés, Salvador Miret; Sibener, Steven J.; Wells, Justin W; Tamtögl, Anton; Allison, William (Journal article; Peer reviewed, 2021)Helium Atom Scattering (HAS) and Helium Spin-Echo scattering (HeSE), together helium scattering, are well established, but non-commercial surface science techniques. They are characterised by the beam inertness and very ... -
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 ...
