  • Thermal Stability of Schottky Contacts and Rearrangement of Defects in β-Ga2O3 Crystals 
    Seyidov, Palvan; Varley, Joel B.; Frodason, Ymir Kalmann; Klimm, Detlef; Vines, Lasse; Galazka, Zbigniew; Chou, Ta-Shun; Popp, Andreas; Irmscher, Klaus; Fiedler, Andreas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract The thermal stability of different Schottky contacts (Au, Pt, and Ni) on (100) β ‐Ga 2 O 3 single crystals grown by the Czochralski method is investigated. Besides the examination of the Schottky barrier parameters, ...
  • Ti- and Fe-related charge transition levels in beta-Ga2O3 
    Zimmermann, Christian; Frodason, Ymir Kalmann; Barnard, Abraham Willem; Varley, Joel B; Irmscher, Klaus; Galazka, Zbigniew; Karjalainen, Antti; Meyer, Walter Ernst; Auret, F.D.; Vines, Lasse (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Deep-level transient spectroscopy measurements on β-Ga2O3 crystals reveal the presence of three defect signatures labeled E2a, E2b, and E3 with activation energies at around 0.66 eV, 0.73 eV, and 0.95 eV below the conduction ...
