  • Diffusion of Sn donors in β-Ga2O3 
    Frodason, Ymir Kalmann; Krzyzaniak, Patryk Piotr; Vines, Lasse; Varley, Joel Basile; Van De Walle, Chris G.; Johansen, Klaus Magnus H (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Diffusion of the n-type dopant Sn in β-Ga2O3 is studied using secondary-ion mass spectrometry combined with hybrid functional calculations. The diffusion of Sn from a Sn-doped bulk substrate with surface orientation (001) ...
  • Migration of Ga vacancies and interstitials in β-Ga2 O3 
    Frodason, Ymir Kalmann; Varley, Joel B.; Johansen, Klaus Magnus H; Vines, Lasse; Van De Walle, Chris G. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Pathways and energy barriers for the migration of Ga vacancies (VGa) and Ga interstitials (Gai) in β−Ga2O3 are explored using hybrid functional calculations and the nudged elastic band method. Considering β−Ga2O3 as primarily ...
