(1996, PBE functional). The ionic cores were described by the ultrasoft pseudopotentials Fe.pbe-nd-rrkjus. UPF, O.pbe-rrkjus.UPF, H.pbe-rrkjus.UPF and the norm-conserving pseudopotential Al.pbe-rrkj.UPF from http://www.quantum-espresso.org. The wave-functions and the charge density were expanded in plane-waves with 40 and 480 Ry cutoffs, respectively (1 Ry = 13.606 eV). Increasing the wave-functions cutoff to 60 Ry does not change the total energy by more than 12 meV/atom and provides the same relative variations of the lattice parameters. For the electronic integration, the Brillouin zone was sampled according to the Monkhorst¨CPack scheme (Monkhorst and Pack, 1976), using k-point grids consistent with the supercell dimensions. k-point grids of 4 4 4 and 2 2 4 were used for the 1 1 1 and 2 2 1 rhombohedral cells, respectively, while a 4 4 2 k-point grid was used for the hexagonal unit-cell. This number of kpoints is large enough to provide fully converged results. Atomic relaxations were performed with the PWscf code£¬ ûÓиãÇå³þÆäÖÐThe wave-functions and the charge density were expanded in plane-waves with 40 and 480 Ry cutoffs, respectively (1 Ry = 13.606 eV).ÖÐÊÇ˵µçºÉÃܶȵĵĽضÏÄÜÁ¿ÊÇ480Ry£¬»¹ÊÇʲô£¿ |
