Table shows that the masses of Ga 2 O 3 polymorphs increase by a factor ranging from 1.3 to 2.4 when compared to those calculated without QP corrections. For In 2 O 3 polymorphs, Table : Binding energies E d b of Ga 3d and In 4d relative to the VBM (in eV), including uncertainties from the broadening of d-levels into bands, the average electron mass m * (in free electron mass m 0 ), average electronic dielectric constants ε ∞ (values derived only from DFT+A-1 /2), the excitonic Bohr radii r B (in Å), and the exciton binding energies E b (in eV) presented without dynamical corrections to dielectric screening. Values are provided from DFT+A-1 /2 calculations and standard DFT (in parentheses). as well as for other polymorphs. Small masses in DFT, akin to those listed in Table predicted by DFT and DFT+A -1 /2, as shown in Table . Discrepancies between theoretical and experimental values may be attributed to the non-parabolicity of the lowest conduction band and its significant modification by the QP treatment within the DFT+A -1 /2 method.
