Disentangling electron-boson interactions on the surface of a familiar ferromagnet
Røst, Håkon; Mazzola, Federico; Bakkelund, Johannes; Åsland, Anna Cecilie; Hu, Jinbang; Cooil, Simon Phillip; Polley, Craig; Wells, Justin William (Peer reviewed; Journal article, 2024)We report energy renormalizations from electron-phonon and electron-magnon interactions in spin minority surface resonances on Ni(111). The different interactions are identified, disentangled, and quantified from the ... -
Enhanced hydrophobicity of CeO2 thin films: Role of the morphology, adsorbed species and crystallography
Mamedov, Damir; Åsland, Anna Cecilie; Cooil, Simon Phillip; Røst, Håkon; Bakkelund, Johannes; Allaniyazov, Atabek; Wells, Justin William; Karazhanov, Smagul (Peer reviewed; Journal article, 2023)In order to guarantee the long-term efficiency of hydrophobic materials in real-world situations, it is necessary that their surfaces are highly resistant to scratching, fouling and misting. Furthermore, for the specific ... -
Initial stages of water absorption on CeO2 surfaces at very low temperatures for understanding anti-icing coatings
Åsland, Anna Cecilie; Cooil, Simon Phillip; Mamedov, Damir; Røst, Håkon; Bakkelund, Johannes; Li, Z.; Karazhanov, Smagul; Wells, Justin William (Journal article; Peer reviewed, 2024)Anti-icing coatings are intended to prevent ice formation on surfaces, minimising the risk of surface-related damage and also reducing ice-related hazards in society. We demonstrate the usefulness of x-ray photoelectron ... -
One-dimensional spin-polarized surface states: A comparison of Bi(112) with other vicinal bismuth surfaces
Åsland, Anna Cecilie; Bakkelund, Johannes; Thingstad, Even; Røst, Håkon; Cooil, Simon Phillip; Hu, Jinbang; Vobornik, Ivana; Fujii, Jun; Sudbø, Asle; Wells, Justin William; Mazzola, Federico (Peer reviewed; Journal article, 2023)Vicinal surfaces of bismuth are unique test beds for investigating one-dimensional (1D) spin-polarized surface states that may one day be used in spintronic devices. In this paper, such states have been observed for the ... -
Phonon-Mediated Quasiparticle Lifetime Renormalizations in Few-Layer Hexagonal Boron Nitride
Røst, Håkon; Cooil, Simon Phillip; Åsland, Anna Cecilie; Hu, Jinbang; Ali, Ayaz; Taniguchi, Takashi; Watanabe, Kenji; Belle, Branson Delano; Holst, Bodil; Sadowski, Jerzy; Mazzola, Federico; Wells, Justin William (Peer reviewed; Journal article, 2023)Understanding the collective behavior of the quasiparticles in solid-state systems underpins the field of non-volatile electronics, including the opportunity to control many-body effects for well-desired physical phenomena ... -
A Photoemission Journey: From Core-Level Spectroscopy on Anti-Icing Coatings to Spin-Resolved Band Mapping of Topological Surface States
Åsland, Anna Cecilie (Doctoral theses at NTNU;2024:442, Doctoral thesis, 2024)Photoemission techniques are among the most used and treasured tools in surface science. In such techniques, the chemistry and electronic properties of materials can be accessed, by illuminating surfaces with light and ... -
Probing the Atomic Arrangement of Subsurface Dopants in a Silicon Quantum Device Platform
Røst, Håkon; Tosi, Ezequiel; Strand, Frode Sneve; Åsland, Anna Cecilie; Lacovig, Paolo; Lizzit, Silvano; Wells, Justin William (Peer reviewed; Journal article, 2023)High-density structures of subsurface phosphorus dopants in silicon continue to garner interest as a silicon-based quantum computer platform; however, a much-needed confirmation of their dopant arrangement has been lacking. ... -
