Physical properties of ?- and ?-Ga2O3are investigated using density functional theory. We utilized the supercell method considering the partial occupancies in ?-Ga2O3. The polarization values of these materials were analyzed to overcome the inconsistency between experimental and theoretical studies. The polarization values of ?- and ?-Ga2O3were ?26.39 and 24.44 µC/cm2, respectively. The bandgap values of 4.62 and 4.27 eV were estimated with the hybrid functional method, which suggested an underestimation of the PBEsol functional values of 2.32 and 2.06 eV for ?- and ?-Ga2O3, respectively. |
