  • Effects of Ga Substitution on the Local Structure of Na2Zn2TeO6 
    Hempel, Frida Sveen; Bianchini, Federico; Arstad, Bjørnar; Fjellvåg, Helmer (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    In the work presented here, we prepared Ga-substituted NZTO (Na2–xZn2–xGaxTeO6, x = 0.00, 0.05, 0.10, 0.15, 0.20) layered materials with a soft chemical, citric acid-based synthesis method and characterized these by means ...
  • Substituted Na-based Layered Tellurates: Synthesis, Local Structure and Na-Dynamics 
    Hempel, Frida Sveen (Doctoral thesis / Doktoravhandling, 2023)
    Solid-state batteries are currently limited by low ionic conductivity compared to the liquid analogue, and improving ionic conductivity is a major concern for commercialization. This thesis focuses on the local structure ...
