    • Electronic Structure and Surface Chemistry of Hexagonal Boron Nitride on HOPG and Nickel Substrates 

      Småbråten, Didrik Rene; Nylund, Inger-Emma; Marshall, Kenneth; Walker, Julian Bradley; Benelmekki, Maria; Einarsrud, Mari-Ann; Kioseoglou, Joseph; Selbach, Sverre Magnus (Peer reviewed; Journal article, 2023)
      The effect of point defects and interactions with the substrate are shown by density functional theory calculations to be of significant importance for the structure and functional properties of hexagonal boron nitride ...

    • A fast, low temperature synthesis method for hexagonal YMnO3: Kinetics, purity, size and shape as studied by in situ X-ray diffraction 

      Marshall, Kenneth; Blichfeld, Anders Bank; Skjærvø, Susanne Linn; Grendal, Ola Gjønnes; Van Beek, Wouter; Selbach, Sverre Magnus; Grande, Tor; Einarsrud, Mari-Ann (Peer reviewed; Journal article, 2020)
      The reaction mechanisms, phase development and kinetics of the hydrothermal synthesis of hexagonal‐YMnO3 from Y2O3 and Mn2O3 using in situ X‐ray diffraction are reported under different reaction conditions with temperatures ...

    • Hydrothermal Synthesis of Alkali Niobates 

      Vadseth, Daniel Stormer (Master thesis, 2021)
      Reaksjonsforholdene under hydrotermal syntese av kalium- og natriumniobater har blitt undersøkt med hensikt å forstå effekten av reaksjonsforholdene på kinetikken, faseformasjonen, morfologien og gitteparametrene. Kalium ...

    • Synthesis of Hexagonal Yttrium and Ytterbium Manganites 

      Eidem, Sigurd Opdal (Master thesis, 2020)
      I denne studien utforskes hydrotermisk syntese av heksagonale manganitter av sjeldne jordartsmetaller, h-LnMnO3 (der Ln er det sjeldne jordartsmetallet), som er en klasse blyfrie ferroelektriske materialer. De sjeldne ...
