Typically, in the density of states (DOS) a double-peak structure with a width of about 0.2 eV followed by a higher-energy satellite structure, which slightly captures the separation Ga 3d 5/2 and Ga 3d 3/2 (In 4d 5/2 and In 4d 3/2 ). Thus, by utilizing the A variation (Fig. ), we adjust the average position of the d band to align with experimental values reported in the literature. This approach yields an A value of 3.2 for correcting the Ga-d level and 1.4 for the In-d level. The CUT parameters for the localized d bands are derived from a previous study, which established their relationship with the atomic charge radius, thereby highlighting their atomic character. In the second step, we applied the standard DFT-1 /2 correction, considering the character of the VBM identified in the initial step. The CUT parameter for the oxygen atom was determined by optimizing the energy gap (see Fig. ).
