Using hybrid density functional theory, we investigated formation energies and transition energies of possible donor-like defects in GaInO3, with the aim of exploring the sources of the experimentally observed n-type conductivity in this material. We predicted that O vacancies are deep donors; interstitial Ga and In are shallow donors but with rather high formation energies (>2.5 eV). Thus these intrinsic defects cannot cause high levels of n-type conductivity. However, ubiquitous H impurities…
