  • Cation segregation observed in an (In,Ga) 2 O3 material thin film library beyond the miscibility limit of the bixbyite structure 
    Montag, S.; Splith, D.; Kneiß, M.; Grundmann, M.; Garcia Fernandez, Javier; Prytz, Øystein; Von Wenckstern, Holger (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Structural, morphological, and optical properties of (In1−xGax)2O3 thin films are reported as a function of the cation composition. A material library with 0.1≤x≤0.64 was fabricated by discrete combinatorial synthesis on ...
  • Formation of γ-Ga2O3 by ion implantation: Polymorphic phase transformation of β-Ga2O3 
    Garcia Fernandez, Javier; Kjeldby, Snorre Braathen; Nguyen, Phuong Dan; Karlsen, Ole Bjørn; Vines, Lasse; Prytz, Øystein (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Ion implantation induced phase transformation and the crystal structure of a series of ion implanted β-Ga 2 O 3 samples were studied using electron diffraction, high resolution transmission electron microscopy, and scanning ...
  • In situ atomic-resolution study of transformations in double polymorph γ/β-Ga2O3 structures 
    Garcia Fernandez, Javier; Kjeldby, Snorre Braathen; Zeng, L. J. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
    Disorder-induced formation of metastable Ga2O3 polymorphs as well as the recovery of the stable state upon annealing attract attention because of the fundamental novelty and rapidly increasing interest in the use of Ga2O3 ...
