We adapt the standard supercell approach to calculate the range of formation energies of each defect type. First, we identify for each defect type, the specific sites in the chosen supercell (see Section 4.5 for details) that result in the highest and lowest formation energy in the neutral charge state (Figure ). We assume that, when different charge states of the defect are considered, these two specific sites will allow us to sample the range of formation energies. Next, for each defect type, we calculate the defect formation energy in multiple charge states but only at the two sites identified in the first step. Ultimately, we are able to calculate the range of formation energies as shown in Figure and 7c and assess dopability of alloys. Overall, this adapted approach significantly reduces the computational overhead while providing a reliable assessment of alloy dopability.
