WebJun 1, 2024 · Partial occupancies of the Kohn–Sham orbitals were obtained using the Gaussian smearing method in a width of 0.05 eV. The electronic energy was self-consistent when the energy change was smaller than 10−5 eV. A geometry optimization was considered as convergence when the change of energy was smaller than 0.05 eV/Å.
