- method performed at fixed volume until the residual forces on each atom were below0.03 eVÅ −1 , and the electronic self-consistency threshold was set to1×10 −4 eV. Spin polarization was included in all calculations. Note that this supercell size was chosen to minimize finite-size effects in the calculation of defect formation energies. The formation energy of a defect X in charge state is given by [23] 𝐸 𝑓 𝑋𝑞 =𝐸 𝑡𝑜𝑡 𝑋𝑞 −𝐸 𝑡𝑜𝑡 (𝑏𝑢𝑙 𝑘) − ∑︁ 𝑖 𝑛𝑖 𝜇𝑖 +𝑞 (𝐸𝐹 +𝐸 𝑉 ) +𝐸 𝑐,(1) 2 where𝐸 𝑡𝑜𝑡 (𝑋 𝑞)and𝐸 𝑡𝑜𝑡 (𝑏
